13. Characters from
Parahumans (
Leviathan,
Khonsu and
The Simurgh)
First why is Player (Fart Attack), Ryukendo, and Brandon Heat doing here
Leviathan gets 4 kilometers worth of space to build up water to just tsunami them, only Brandon can handle Khonsu aging them to death but he can be trapped in a time field and while he could still shoot he can get past the regeneration and durability of Khonsu which is basically incap, none of them can handle The Simurgh's range, M class telekinesis, and mind hax.
Dio can't truly harm them and none of his ways to ignore durability work so. Khonsu does get to keep Dio in a time field until sunrise unless Dio becomes able to stop time forever before that point, the other two basically do the same thing they did before.
Bunny can't hurt truly hurt them either so I think she loses the war of attrition because they can harm her more consistently and The Simurgh just mind haxs without killing her.
Korosensei his mind hax might be layered enough to work however the also seems to be meant to work on humans specifically and he gets walled until he dies.
