Father Gregori looks like a missing texture Master Chief

[Zazabar]

I didn't download a master chief. =\ I tried searching for any master chief files and deleted them and all it did was make the texture missing. Where could I possibly find these files and bring back my original guy without totally deleting the entire folder?

Look in the models folder, not the materials folder.
Common mistake.
Look for files on Gregori, not on Master Cheif though, since it's replaced him. It'll be called monk.mdl or something alone those lines.
