He technically did die, that's why I put "died" in quotes.
Also>Because despite being fully capable of killing Batkek, he instead uses his powers to erase Batkek's gay multiverse and goes home as a result.
Lol he was nowhere NEAR capable of killing batkek he was trying his absolute HARDEST and ended up "dying". And it wasn't even his CHOICE to go home as the moment he comes home he's like "what the fuck happened??? I was literally fighting him".
