–Sol Badguy to Dizzy
Sol Badguy is the main protagonist in the Guilty Gear series and Ky Kiske's eternal rival. At first glance, he is an aloof, anti-hero bounty hunter, whose apparent laziness and gruffness belies his terrifying fighting ability, amazing intelligence and emotional depths beneath that brash exterior.
Creator Daisuke Ishiwatari designed Sol in many ways to reflect his alter-ego, and also recorded Sol's in-game voice acting (the voice acting for GGXX's Story Mode and Drama CDs however, is done by Hikaru Hanada).
Sol's normal character design depicts him as left-handed, with brown hair and reddish-brown or golden eyes with slit pupils (the latter of which is to distinguish his true nature as a Gear), wearing a tight, black undershirt with the top half covered by a red, sleeveless jacket along and white jeans. His headband bears the words 'Rock You', a reference to the Queen song "We Will Rock You", while his belt buckle has the word 'FREE', a possible reference to Queen's song "I Want To Break Free". Sol's character design also contains a pair of black, fingerless gloves, red shoes, a drape of red cloth hanging down beneath his buckle and a multitude of belts, including a lone one on his left bicep. Sol fights using a blunt, rectangular sword known as Fuuenken (Fireseal) through which he releases a range of fire-based attacks.
Of note is that Sol is officially left-handed. In recent official artwork, Sol, as Frederick, was depicted with blue eyes and sported shorter hair.
Sullen and unrefined, Sol only speaks to others when absolutely necessary. This is reflected in everything he does, and his fighting moves, while rough and unpolished, are executed with absolute precision. He is known to be rude and impatient towards those who wish to interact with him, whether they are friend or foe. He is also quite stubborn when he is in pursuit of a goal or when he decides to take action regarding certain matters, never allowing the opinions of others to dissuade him once he's made up his mind. Overall, Sol is not a friendly man, but he is not an inherently evil one neither. He is an individual who prefers to convey his intent through actions than words. And while he cynically mocks those who speak of "justice", he has demonstrated a staunch sense of righteousness that motivates him to prevent anything that may potentially threaten the world and the peace that's been established after the horror of the Crusades.
His actions have also proven that he is quite compassionate in contrast to his anti-social persona. He refused to harm neither Dizzy nor Solaria due to their innocence and kindness, despite the fact that they are Command-Type Gears who possess enormous power that puts them on equal footing with Justice and the ability to subjugate Gears to their whim; he even gave a Gear-Cell limiter to Solaria so she can control her power and rescued Dizzy when she was possessed by Necro and went on a rampage. He also spared Testament on several occasions despite being a dangerous and powerful Gear due to him being the son of his friend and mentor, Kliff, as well as out of mutual sympathy since they are both humans who were forcibly converted into Gears. He also takes in Sin at the behest of Ky and Dizzy so that he would not be placed in danger by the Conclave. He even offered a prayer for Justice's soul to find peace in the afterlife after he defeated her for the second time. He also swears to save Elphelt from her fate as a tool of the Universal Will. It is seen through the course of the series that Sol has much deeper emotional depths than he normally doesn't display towards people.
Pre-Overture Sol constantly roamed the world alone, and kept everyone at a distance, only stopping to fight when it was necessary or to intervene in cataclysmic events. His aloofness and cynical attitude was developed as a result of his betrayal by his once best friend and colleague, Asuka R Kreutz (Known throughout the series as That Man) through the death of his love, Aria and transformation into a Gear. Since then, Sol maintains his aloofness and cynicism throughout the series, primarily to avoid hurting anyone due to his nature as a Gear. As the series progresses however, his clashes with many of the series characters slowly begin to change his outlook, especially his rival Ky Kiske and Ky's son Sin, who he reluctantly takes as his apprentice. During the final battle against St. Maximus Populi Ariels in Guilty Gear Xrd -Revelator- Sol admits to her that the world where he kept himself distant to others, was worth saving, and finally acknowledged that despite what he was and his fear of the future, he was no longer alone in the world.
His exact history is unclear, but it is known for certain that Sol's real name is Frederick. Originally, he was a scientist who majored in Magic Particle Physics and was previously working on a project known as Saint Oratorio before he joined the core team of the Gear Project. He was not only one of the lead scientists of the Gear Project, but is also the Prototype Gear from over a hundred years before the events of the Guilty Gear games. In 2016, after he received the devastating news of Aria's illness, he is betrayed by his colleague and close friend, Asuka R.Kreutz, who forcibly has him converted into the first Prototype Gear. Somehow, he managed to escape the lab and tried to discover a means to return him to his human form, leading him to creating his trademark headband. His headband is actually a Gear-suppression device which prevents him from giving into his Gear nature and losing his rationality, at the cost of suppressing much of his power. The headband also conceals the red brand on his forehead, the telltale mark that would expose him as a Gear. As a prototype, he is immune to the orders of Commander-Type Gears. He was personally acquainted with That Man prior to the Crusades. In Guilty Gear 2: Overture, this headband suppression device seems to be beginning to malfunction, explaining the increase in Sol's strength. That Man later explains the malfunction and Sol's increase in power is due to his body and powers evolving.
After he had constructed the limiter Headguard to maintain his human form, he made it his personal mission to destroy all Gears so that they could not be used for war. He destroyed several Gear Plants, which would eventually earn him the designation "Badguy" as authorities could not identify him. When he caught news of the completion of Justice, He created the "Outrage" in response, which he called a supreme Anti-Gear weapon. The Outrage is actually not one weapon but several - eight components called "Jinki" (Sacred Treasures), which greatly amplify their wielders' magical ability. The reason the Outrage was split into the eight Sacred Treasures is because the power of the complete Outrage was far too cumbersome for Frederick to control as it had no predetermined limits to how much Mana it could generate, and could potentially destroy the world if its power was not properly regulated. Only four Outrage weapons are currently known to be active - Sol's own Fuuenken (Fireseal) that he combined with Senga (The Flashing Tooth) to create the Junkyard Dog MK.3, Ky's Fuuraiken (Thunderseal), and Anji Mito's twin fans, Zessen (Unparalleled Fans). The other three are supposedly in the custody of the United Nations, and Slayer is also in possession of an unknown Sacred Treasure.
Frederick also saved Kliff Undersn (one of the leaders of the Holy Order and the one who named Ky Kiske leader of the Holy Knights) when Kliff was still a young boy. He would later encounter the Nightwalker, Slayer, who would bestow upon him the name "Sol" and would act as a mentor of sorts. Roughly half a century later, he was himself recruited into the Order, as a bounty hunter named "Sol Badguy". Sol took part in the Crusades, ironically becoming one of the best fighters on the human side. At this time, he was a member of the Sacred Order of Holy Knights (Seikishidan). He acquired the nickname "Corrupted [or Immoral] Flame" (Haitoku no Honoo) during that time, a name that such figures as I-No and Justice use for him later. However, he later became disenchanted with the methods of the Sacred Order. At an unspecified time, Sol fled the order, taking with him the Fuuenken, which the Holy Knights had come to consider a sacred treasure — the theft earned him Ky Kiske's enmity. Ironically, Sol himself forged the Fuuenken.
In 2175, Sol faced Justice directly. The two fought, and Justice won, also discovering that Sol was a Gear (but not his true identity as the Prototype Gear). Justice attempted to assert her power as a Commander Gear to control Sol, but was unable to do so. Exploiting her confusion from the fight, the Holy Order, led by Ky Kiske, sealed Justice away, bringing the war to an end.
Canon states that Sol was the winner of the Tournament, and it is here that Justice discovers that Sol is, in fact, Frederick. Justice, in her dying words, comments that she wishes that "the three of us" could talk one last time, and Sol swears to kill That Man.
Guilty Gear X
Sol has three endings, all of which involve a fight against Dizzy, who has a half-million World Dollar bounty on her head. However, he spares her life in all of them, losing against her in his second ending, and judging that she isn't a threat to the world in the other two. In his third ending, we see a conversation between That Man and one of his servants, in which That Man cryptically says "To think there was a daughter... most interesting". It is revealed in the Drama CD Side Black to that this a reference to Justice being Dizzy's mother.
Guilty Gear XX
His storyline here involves chasing down I-No. His first ending, after he defeats I-No, leads to a direct confrontation with That Man. That Man casually deflects all Sol's attacks, and says that Sol is needed because soon a greater battle than the Crusades will occur. In Sol's second ending, Slayer informs him of the Post-War Administration Bureau's interest in Dizzy, which catches his interest. In the third, he fights Dizzy, who had been possessed by Necro after I-No knocked her off the Mayship, and sends Dizzy on her way to meet Johnny and May.
Guilty Gear XX Λ Core Plus
His story here follows directly after the previous one in that he is hunting I-No down, as well as investigating the Post-War Administration Bureau. Depending on the player's choices and actions, Sol may do battle with Ky, and upon further investigation, encounter Crow and defeat his copy of Justice, before encountering I-No again and being pulled into the past and being forced to battle his past self, Order-Sol.
After their battle, I-No slyly kills Order-Sol. Depending on the players choices and/or if they did not use a continue at all, Sol will either be destroyed by the resultant time paradox as That Man laments Sol's falling for I-No's trickery and implores him to live (Path 2), or he will resist it and obliterate I-No, before returning to the present and battling Ky (for the second time if players choose the first option upon encountering him at the P.W.A.B. branch). After the battle, Ky makes Sol promise that they'll meet again before they go their seperate ways (Path 1).
Guilty Gear 2: Overture
Sol Badguy has taken in a young man named Sin as his apprentice, and travels the world with him as bounty hunters. During their journey, they came across a wanted poster with Sol’s picture on it. Sol figures that the poster is just Ky's way of asking for help. Shortly after, he is plagued by a headache and the pair are attacked by the Vizuel, the servants of Valentine. The Vizuel had the upper hand until a voice introduces Sol to a new power, the Soul Sinker. This allowed Sol to construct Servants of his own from his soul, leading to their victory. The voice later introduced himself as Izuna, a resident of the Backyard. Izuna told Sin and Sol that the Vizuel were seeking out and destroying Gears. Their main area of interest was the kingdom of Illyria.
Izuna, through a series of warp gates, takes the pair to Illyria. There, they meet Valentine for the first time. Sol’s head ached again, and he was shocked by Valentine's resemblance to Aria. Sol battled her and the Vizuel with the help of Izuna’s powers. After the fight, the group made it to Illyria Castle, where they found Ky in a powerful binding spell. They met with Raven, who Sol recognized as That Man's servant, and the two battle.
After the fight, Sol left Sin to guard Ky, while he went to meet Dr. Paradigm who can release Ky's spell. Sol was shocked to be brought to a colony of living and self-aware Gears. After learning that Sol is Frederick, Dr. Paradigm agreed to help the king. Sol then accompanied Dr. Paradigm to Illyria to release the seal placed on Ky. After realizing that Sin carries the Gear cells Valentine needed, Sol and Izuna left the others to defend Illyria Castle while they chased after the young man.
They were too late to stop Valentine from kidnapping Sin. Sol and Izuna chased after them to Bel Canto Valley where they fought a brainwashed Sin. After Sin came to his senses, the group took off after Valentine. Thousands of Vizuel stood in their way. To their surprise, Ky, Paradigm, and the knights of Illyria arrived to take on the fight. Sol, Izuna, and Dr. Paradigm went on ahead, leaving Sin and Ky to take on the Vizuel.
Sol and the others reached the gate to the Backyard, but it was already closed. Just before all hope was lost the gate opened and a lone figure came out, That Man. Sol unleashed his evolved Dragon Install in order to fight That Man. During the battle, That Man seemed to be testing Sol, and informed him about Valentine's intentions. When the battle ended, Sol was unable to damage That Man. As he left, That Man gave the group an effect that would enable them to survive the immense pressure of The Backyard.
The group entered the Backyard and caught up to Valentine. The Key was already in motion and the Cube was starting to open. In frustration, Valentine transformed into a Justice-like monster and battled the late arriving Sin together with Izuna and Dr. Paradigm. Meanwhile, Sol was busy stopping the Cube from opening. He succeed, and Valentine seemed to give up fighting. She appeared as if she was going to self-destruct. Sol told the others to escape the Backyard while he remained back to fight yet another form of Valentine. In the fight, Sol battled both Valentine's immense body and her soul. In her soul, he would hear a rush of her emotions and memories. Once he laid the final blow, the last thing she said was his true name, Frederick. After the fight, Sol found himself in a white space, unable to return.
While there, That Man came before him yet again. He revealed that Valentine is involved with “A Merciless Apocalypse”, an event that Sol is to take part in. Sol confirmed with That Man that Valentine was a copy of Aria, Sol’s former lover, who is implied to be the woman That Man turned into Justice. With That Man's help, Sol was able to return to the real world and reunite with the others.
Guilty Gear Xrd -SIGN-
Sol has been traveling with Sin when he heard Ramlethal Valentine's declaration of war on humanity. After a brief talk with Ky, he decides to fight her, wanting 1 million World Dollars of bounty in return. Ky and Sol meet in Neo New York, where they fight before heading out to Japan to confront Ramlethal. After fighting and beating her, the entire declaration of war turned out to be a trap to lure Sol out. After people of Babylon are obliterated by the giant explosion, Ramlethal grabs Sol, intending to self-destruct, killing him with her. However thanks to Elphelt on disabling Ramlethal's self-destruct and rendered her powerless, Sol able to subdue her. When he's about to kill Ramlethal, Ky suggest to keep her alive and taking her into custody to find out who sent her. During Elphelt's introduction, Sol despise her and believe that she may betray humanity in the end. While Sin and Elphelt integrate Ramlethal to develop her emotions, Sol patrol outisde the room where the three plays there.
Sol's gameplay consists of mainly rushdown aspects, so just about all of his damage is dealt up close. He's probably the most average character in the cast and is easy to learn, and has a couple of very useful normals and specials like 5K and Volcanic Viper, but he can be a very high risk/low reward character if some moves are used recklessly, like Grand Viper and his Overdrives for example, though this becomes less of a problem in several retweaks of the GGXX games. In the early days of GGXX, Sol's infamous dustloops devastated several of the cast, but as the revisions went on, Sol's dustloops were more tweaked, and his Sidewinder loops as of GGXX Slash (much more so in Accent Core) become rather more character specific, forcing to higher levels of play. He also lacks solid high/low mixups and tends to take a lot more effort to play, requiring use of fundamentals and unorthodox-defense-openers to get in his rewarding, albeit average-damage.
However, he has one mechanic that's been associated with him ever since Slash; the clean hit mechanic, which allows him to use specific moves (Grand Viper, Bandit Bringer, Fafnir and Sidewinder) to land a hit dead-center on a character which in turn increases damage, hitstop and hitstun, allowing him to drag his combos on for longer and to get more overall damage off. However, ever since Slash, moves such as popular power-up Overdrive Dragon Install have become much more risk than reward. Another thing his clean hits can contribute to in Accent Core is the damage of his Force Break Tyrant Rave ver. α; the more clean hits Sol has connected with, the more damage the said Force Break can inflict based on the amount of clean hits landed before it resets.
Sol went through significant tweaks between Accent Core+R and Xrd due to the game being based around older versions of the characters. In +R's case, Sol has regained a bit of his dustloop, but now regains his normal version Fafnir along with gaining a new Force Break version of his Sidewinder and a Dragon Install-only version of his Tataki Otoshi move; the latter attack can now greatly extend Sol's combos with free clean hits even with horrible positioning.
Notably though in Xrd, he loses the Sidewinder loop (due to Sidewinder not appearing in his moveset), which causes the dustloop to regain importance in combos. Riot Stomp now has two hits, first one being the kick, with a follow-up stomp attack afterwards that opens up combos and leaves Sol safe if blocked. Dragon Install has also been greatly revised. It briefly transforms Sol into a new form and greatly powers up all of his moves even more than before. New special attacks include Kudakero/Break (Shatter), an aerial dive kick with a fiery pillar upon landing and P.B.B., a powerful, Dragon Install-only aerial command grab. Still lacking the mixups available to a lot of the cast, Sol benefits greatly off the new Roman Cancel mechanic, making his pressure safer, longer and overall stronger, leading to his command throw more often; which overall leads him to be considered among the highest-damaging characters of the cast.
Main article: Sol Badguy's Command List
Powers & Abilities
Sol Badguy is often noted to be one of the greatest fighters seen in the Guilty Gear series. Being the Prototype Gear, Sol was immune to the control Justice had over other Gears. Due to his Gear state, he possesses longevity, degrees of regeneration and in some cases, invulnerability. While he does not practice any fighting style in particular, his skill level seems to be second to none. He is also a master swordsman and doesn't appear to favor any particular type of blade, no matter the size.
His fighting style is well-known for being self-taught, without much form with a huge focus on all-out brawling, and also being noted for his left-handed reverse grip. However, throughout several years, Sol has refined his fighting style into a more personal form that also involves solid control over his flames. Attacks involved in this style are often crude in nature, such as headbutts, wide-swinging strikes, slams, fierce punches and kicks. Much of this is usually due to Sol's laziness preventing him from reaching a more martial level with his form of fighting. It is also because Sol prioritizes precision in his fighting style above all else.
Sol is stated to be a genius practitioner of Magic Arts outside of his natural flame magic. This is evidenced by his creation of the Sacred Treasures, each being a powerful magical amplification device imbued with a different element and having a special quality.
Sol's weapon of choice is the Fireseal (Fuuenken), a uniquely designed sword with a rectangular blade, the blunt part which seems to have an exhaust/engine-like device that spews forth flames. The weapon itself is capable of generating high-power flames, which he can use to augment both his physical and sword attacks. He often fashions this fire into ground-bound projectiles. He later upgrades to the Junkyard Dog MK III in Guilty Gear Vast Edge and -SIGN- , which is actually a combination of two Outrage weapons - The Fireseal and the Flashing Tooth. Sol designed Junkyard Dog MK III with a secondary function to transfigure into a long-range cannon that can fire magical bullets packed with his own flame magic as well as an extremely powerful energy spell called Saint Oratorio, which can release intense bursts of magical energy. However, the backlash from unleashing this spell is tremendous, causing it to not only cause significant damage to the target and environment, but the user as well, which is why Sol utilizes it sparingly.
Additionally, thanks to Izuna's modifications to his magic during the Baptisma 17 incident, he has also tapped into the ability to use the Soul Sinker system, a powerful and almost obscure summoning ritual that allows him to manifest his soul(also known as a Master Ghost) into physical reality and create Servants, powerful familiars born from his soul. Though, due to his relative inexperience with this magic and risks involved in manifesting his Masterghost (which would result in the obliteration of his soul should it be destroyed), he does not use it often. He has made use of the matter displacement aspect of this spell to create materials that he can use to construct his weapons and even a new vehicle, the Fire-Wheel MK II, which he needed after his Servant.
Whenever Sol becomes serious or desperate, he may rely on his own latent Gear powers to give him an extraordinary boost. Whenever he first does so, his body flashes a silhouette, as if to contain an inner beast. In truth, this is him holding back his transformation. When he was a bit younger as a Holy Knight, the silhouette has wings and a long tail, which suggests that in his current state, he has been able to repress it almost entirely. However, due to the encroachment of his Dragon Install caused by the Flame of Corruption, he will transform into a dragon-like creature with his blade wrapped in infernal flames shaped into a sword when properly provoked, allowing him to go toe-to-toe with That Man.
However, it had been stated that even in this form during the fight, Sol had not actually went all out, nor did he remove the Gear-Cell limiter on his head, which may suggest an even more drastic transformation should he release all of his power. He has since learned to repress his Dragon Install into more humanoid forms as seen in Vastedge and Xrd.
