In Mega Evolution Special IV, Alain fought ten Trainers with Mega Evolved Pokémon in a row under the condition that he had to return his Mega Stone and Mega Ring to Lysandre had he lost to one of the Trainers. Despite not being able to rest between battles, Alain was able to defeat the first nine Trainers. During the middle of the challenge, he still refused to let Mairin travel with him as she would've been in danger. Unfortunately, this led to Chespie walking in on an experiment which subsequently overloaded, exposing Chespie to near-fatal levels of the energy produced as part of the experiment and causing it to fall into a coma.
Alain fought Malva as the final Trainer. Alain has known about her before as she was part of the Elite Four and Malva has heard about Alain's loss to Siebold. Alain was not convinced that he was going to lose to Malva. Alain pitted his Charizard against Malva's Houndoom and true to his word, Alain was able to defeat Malva. After battling Malva, he went to see Mairin from behind a corner. Upon discovering this and hearing a broken, sobbing Mairin begging Lysandre to assure her that Chespie would wake up, he started to feel that it was his fault and, believing that the Mega Evolution system would restore Chespie's health, set out to complete it in order to bring back the cheerful Mairin he knew. After leaving, a Trainer with a Mega Banette stopped him and they had a battle.
