long range, Psy Blast for 4 damage with 10 attack that turns mid-dial to a 12 attack pulse wave, regeneration that can bring him back on his first clic, and all that for less than 130 pts.

Hands down, the new Prof. X. Couple him with cheap enhancement (Researchers) and perplex, ANYONE on your team with common keyword can Psychic Blast with a 13 attack, 5 damage, 8 range (or more...SHIELD, perplex). Add Elite Sniper for 20 points and anyone can be a Stealth-ignoring Sharpshooter during said attack!
For cheaper points, Karnilla is amazing, as is Moonstone

How is Catwoman indomitable? Everyone deserves it before her, even Aunt May.
