>>8117917Putting on some nerd glasses here. It depends on how similar their powers are. Ame can travel forward and backwards through time, she's the one doing the travelling and she's restricted to those two options. If Kronii can actually manipulate it, meaning she can stop it, reverse it and fast forward it 'outside' of herself, then she has the upper hand.
If these council Holos have mortal bodies, then in a fight Ame at least has a chance if she gets the jump on Kronii first. If it's not a one hit kill then Kronii can just reverse time and get Ame back. But then Ame can just do the same thing in return. In other words Time Travel is an extremely busted ability in any fiction.
