I thinks it was an anime but if he was there then he would end the anime i. 1episode (if he Does not hold back bcs the creators said if he went full power the game would not be fun)
The Doom Slayer only beat hell because he needed to and because they killed his bunny, I think he could have very easily beaten the 9 realms if he wanted to(and if they existed in doom lore).
Im just gonna point out one thing the demons didn't just "killed his bunny" they killed his entire family like his wife his daughter he's whole family very very brutally
Kratos:mi hijo murio loki y su mundo morirá cómo tributo Dioses y brunilde:se acabó todo 3 Doritos después El fin de mi venganza a comenzado con el fin de los dioses y valkiries
While he wouldn't know it for most of his life, Kratos was a demigod as he is the son of Zeus, but he would later become a full-on god, the God of War to be precise, after killing Ares. After years of serving the Greek gods, Kratos became disillusioned, and resentment towards the gods grew strong.
Ah yes kratos the god executioner You can call him to some to your universe to kill gods but it will come at a price That price is 1 wish for him and his son
Actually doom slayer is 1 vs infinite hells that's his job to cross dimensions if heaven or hell gets out of control and destroys that dimension because once he'll or heaven is gone it becomes unbalanced therefore destroying the dimension
