Red

Story
Unknown.

Abilities
Red is a technological genius, able to invent all sorts of devices. Because of this, although she's not very good at fighting (reflected by her level of 3), she could easily find a way to take out most enemies no matter how powerful they are, if given enough resources, information, and time.

In other words, a theoretical fully prepared Red is much closer to being level 11 in the sense that she could hypothetically find a sure-fire way to defeat level 10 threats.

However, this sort of planning might easily take weeks, months, or even years, during which time if the level 10 threat in question knew of it, they would have plenty of time to stop her with comparatively little resistance.

Ultimately, there's no real way of quantifying Red when she's planning things out, except that if you're not careful, this level 3 genius will kick your ass no matter who you are.
