Looks like Y/n aka SMG5 is suffering some real brainrot as the infamous evil version of Max Pro from the Twiddlefinger (A Jeffy Endless Aethos Parody) FNF Mod is possessing his body for himself and its up to Mario from the SMG4 Universe to defeat the evil monkey and save his best friend from his control with the power of his Devil Mario form for a much needed power boost to take out the enemy.
