Credit goes to AndrewBreslinabrb for the setup.
I tested his Fuzzy Guard setup on the majority of the cast, and my results show below.
Wesker, Doom, Dorm, Skrull, MODOK, Trish, Storm, Magneto, Sentinel, Haggar, Hulk, She-Hulk.
Doesn’t work on anyone else. I didn’t test Ammy and Joe for obvious reasons.
Some characters get hit by the setup, but when blocking their hitbox becomes shorter. These characters are:
Chris, Shuma, Tron, Task, Capt, Thor, Iron Man, Dante, Spencer.
I don’t think the previous is important though. If you guys find anything out, feel free to share.
