He's getting sick of fighting everyone now. You can Remix and fight him, but he will try to end the battle as fast as he can. (basically, he will attack at unrealistic extremes) there isn't exactly any rules, other that you cant revive. You can also "spare" him which causes him to dissapear. You win the battle if this happens. His sanity level in this project is below 5% 1% or 0% when "Smiling" 20% when crying
