Yeah we do know what Dragon Irene can do. It's not enough to take down Suzaku. It's not even enough to take down Erza.no dragons allowed because we dont know what eileen dragon could do. dragon eileen might be able to one shot suzaku too
and yes i agree, human selene wont perfrom that much better than human eileen against human aconologia
No, they won't. Selene will be able to keep pace with Acno even when he's going all out. She will be able to match Acno in magical attacks, because their magic is on the same level. Irene gets overpowered if they trade magical attacks head on, and gets blitzed the moment Acno decides to go all out with speed. Irene got blitzed by Wendy, and Acno can move faster than August can perceive.
