Because when you see one , they aren ' t being used for what they were made . <| sep |> One raspberry tea and abortion comin up <| sep |> Israelis and Trump tards . really ? <| sep |> Even if that ' s the case . we know for sure that things in the past have happened , too . That doesn ' t mean there aren ' t plenty of fictional characters more than capable of rewriting the past with a snap of their fingers . Many characters are easily capable of overriding things as minor as time or even causality itself . For example , I addressed your Norse ! Odin vs Galactus example by pointing out that Galactus ' Ultimate Nullifier will solve the problem . The UN can erase entire timelines without issue , so it has no problem erasing Odin ' s existence even from past and future , thus deleting him from the Ragnarok prophecy and bypassing the protection . Plenty of other characters are easily at or above that level of power .
