Impenetrable defense, and extremely effective offense. Touma's anti-magic/anti-esp hand is probably the most effective counter.

Misaka's best possible attempt against Accelerator would be an indirect attack, such as destroying all the oxygen around Accelerator to suffocate him. Except if he figures out what she's doing he can counter that easily by generating wind.

So a powerful nuke might kill him by depriving him of oxygen.

An indirect magic attack might defeat him- such as a spell that cause people hostile to the spells target to pass out- but even that may depend on whether or not the is a vector involved and whether Accelerator can identify that vector. (For example, this hypothetical spell might have a vector involved in identifying who the hostility is pointed at- in that case Accelerator could theoretically counter it directly).

Is there a vector-less attack? That is the first requirement to bypass Accelerator's passive defenses. Then you'd also need to have it be immune or shielded from an active attempt at disruption using vectors.

Attacks that aren't science based can.
