Magic doesn't actually exist in the Ben 10 universe, actually as revealed in the Alien Force episode "What Are Little Girls Made Of?", by Verdona Tennyson magic is actually called Mana. And Anodites are beings comprised of pure energy that are able to manipulate Mana to perform anything. So supposedly, anybody that is capable of casting spells must be part Anodite and have the "spark" (as Verdona described it), because that is the only reason why Gwen is able to use "magic".
