Hello, if you mean the Bakugo model that's available on Deviant art https://www.deviantart.com/bakugos/art/MMD-Katsuki-Bakugo-Hero-Costume-782119392 yeah I used that model. It seems all you did to it was adding an angry emote, but sure np I will add your name on credits when I do the next world update. That will probably be today or tommorow.
Zombie on a future VRChat update all garbage unoptimized avatars will be blocked by default for all users. You may not care about performance now but don't say I did not warn you.
The model Eagle linked on comments is a total lag generator. Over 10 materials, multiple skinned mesh renderers and an absurd amount of dynamic bones. If you wanna be a performance killer in public worlds go for the other model, if you actually know what you are doing use this one instead.
