oE Ai can be found when a certain sub-glitch of the Pomeg Berry Glitch is performed. The player must enter a battle when all of his/her Pokémon are fainted. Then, on the first turn, the player must Revive a Pokémon that is not in the first slot of his/her party. The game will then ask the player if he/she would like to switch. The player must select Yes, but then select Cancel. oE Ai will then be sent out.
