Normally, Undine is a simple light blue wing upon Dizzy's back, but she can shapeshift into various other forms, one of them is the form most recognize her in, her Angel form. While in her Angel form, Undine has no legs, instead her hip is attached to Dizzy's back where the wing itself lays, making it seem as if Undine cannot leave her host. She looks like a traditional Angel, with long flowing hair, a long flowing cloak, and a single wing, though her entire color scheme is of light blue hues.
As a Spirit Guardian System, she takes her duty to protect Dizzy quite seriously. Unlike her black-winged counterpart, Undine appears to be more reasonable and isn't quick to violence. She also displays a motherly nature towards Dizzy such as cradling her when she collapses from exhaustion and tends to distract her to keep her from seeing Necro's brutality. She appears to represent Dizzy's compassionate and quiet nature. However, she can be immature at times, seen in her bickering with Necro, where she often antagonizes him by sticking her tongue out at him in mockery. She is also said to have a temper to terrifies even Necro, who is supposed to be a manifestation of Dizzy's negative emotions.
Powers and Abilities
Undine can create ice spires to appears surface to attack, summon electric blades, conjure flying scythes made from ice magic, water bubbles, as well as flying piranhas made of ice that can fire thin laser beams. She can transmute herself into pure blades of ice in her Wing form. She has recently shown the ability to conjure a mirror barrier that can repel attacks or enemies. It is unknown if she can leave Dizzy's back or if she can fully manifest herself by possessing Dizzy's body, as Necro has done.
It is also implied in the GG World Library Database that Undine may actually be more powerful than Necro.
- Undine and Necro can be seen distracting Dizzy during some attacks that Necro performs on Dizzy's behalf to spare her the discomfort of witnessing Necro's brutalizations. For example, during her Dust attack, Necro will reach over to Dizzy's other side and tap her shoulder, causing her to look at Undine while Necro hits the enemy with an uppercut; Dizzy is only able to see the foe flying in the air.
- Undine and Necro do not appear to get along very well. In some taunts, for example, they can be seen bickering with each other.
- After winning, Undine will be shown catching a worn out Dizzy with a gentle smile on her face.
- It is stated in the Guilty Gear Xrd Library Database that while she is generally benevolent, Undine has a temper that frightens even Necro.
