I had a feeling I was going to get nailed for that one.
No worries, I even had to tell ChrisG and F. Champ about it. Oddly enough, everyone seems to know that Wesker can just superjump -> gunshot, though. You'd be surprised what answers characters have to Stalking Flare. There are only a handful of characters that have no answer to it at all.
Clearly Wesker's projectile counter is the superior choice.
Hahaha. Answers for your characters (assuming no DHC from Dormammu):
X-23: Weapon X Prime
Wesker: Superjump, d.H
Magneto: Magnetic Shockwave
Any character: superjump + call projectile assist. Stalking Flare will follow the point character up, and the assist will hit Dormammu.
Stalking Flare is one of the most overrated hypers in the game.
