This is human Irene and the Fusion Witch Twinrova. When their children are involved, they can be quite evil, whether it benefits or screws over the child. But which of these two would wipe out the other?
Depends, what's the exact AP of dragon irene without it? cos the 'at least' in Twinrova's tier makes me think they might hold a comfortable advantage making the fight unfair if Irene cannot use her strongest move.
the value might not matter since you could argue that irene could tank her meteor given that it was intended to strike right in front of her and she probably wouldn't use an attack that would kill herself as well at that range.
