MISAKA sisters are the most broken, that is all, being able to attack from up to 3 bloody points at the same time (summon misaka sister, summon partner, and firing with main misaka) and doing incredible damage in the process (easily 1500+ with grab misaka, damage doesnt matter as much with Sniper and Grenade misaka as they Knock down the enemy)

Mugino is broken too, she can just dance around her enemies and beam spam, but accelerator murders her. Accel himself is pretty hax too, but doesnt have the sheer firepower of Misaka unless you get them in a corner, and spam earthquake for insane combo (ive done 0 to death before, but that may be coz the CPU sucked). Accel's basic triangle grab throw does up to 1600 with wall crash, which is fantastic as it outdamages most character's combos, has reflect frames and is almost instant, thus making it hard to interrupt with summon, especially if you pull it out of his godly vector dash

Runners up for overpowered characters are Kuroko and FUZE.
