Is there any anime or manga character stronger than Saiki? I mean he can literally erase earth in a second if he doesn't have his antennas. He can also reverse time, and see the future. Another thing is that he can turn anyone into rock once he sees them. The only character I feel can kill him is Light, because he could just kill him with just knowing his name (without interacting), but can't he just return time. Are we even sure he could die?
