Also, when his EVA unit absorbed the S2 unit from the Angel, it essentially become free from the confines of the external power supply :3
Non mecha wise, I might have to say Lucy from Elfen Lied. Although her vectors are limited to close-ish range, her power is beyond comprehension IMO. Her only downfall is her reverting to her "other self" randomly. As much as I love Lucy's good side (Nyu), I kind of like her true self ^^;
