Upon vanquishing M.EXE, the protagonist seizes a mysterious box, only to discover it contains a malevolent poison mushroom that alters his physical appearance. He now appears slimmer and his color palette has undergone a complete transformation - his shirt is now black, and he bears a distinctive scar in the shape of an "M" on the front.

M.EXE: YOU WON'T GET AWAY THIS TIME AAHAHAHAHAHAHAHAH
