Suggested by iKnowledge Irene is a powerful mage and one of the strongest Fairy Tail characters in existence. She was wiping the floor with everyone she fought and Wonder Woman won’t be able to turn the tables here. Irene’s magic pressure is so dense that even approaching will be tough for WW. Wonder Woman has a very high level of strength and speed on her side, bur Irene is very durable. I’d say that Wonder Woman’s speed will be her best asset here since that isn’t Irene’s specialty, but ultimately it won’t be enough to overcome Irene’s other advantages. Irene Belserion wins.
