Prior to the start of the series Xerosic owned Malamar as a Inkay. He was showing signs that he wanted to evolve, but Xerosic couldn't figure out how to make it happen, trying everything at his disposal. Lysandre notices this and grabed Inkay and turned him upside down. Inkay immediately evolves into Malamar, much to their shock. Lysandre explains to them that when all your options are gone you may have to turn your thinking upside down. This message left a strong impression on both of them.
In Malamar Traps, Malamar used his Hypnosis to put X's group to sleep so they could offer no resistance. Although he got most of them it is revealed that X and Croaky were unaffected due to X having water in his ears and Croaky using his tongue to block sound. Malamar and Croaky begin to battle and Malamar is quickly stunned after Croaky grabs Malamar with his tongue and slams him into the ground. Malamar lays low for a few moments and takes the opportunity to attack X, who dodges and slams Xerosic into the ground. Croaky attacks with Bubble to lower his speed, causing Malamar's Ability, Contrary to activate. Using the new boost in speed Malamar uses Hypnosis, but Croaky proves to still be faster. Hoping to wake up the others X has Croaky use Double Team to spread out. Furious that everyone might wake up Xerosic has Malamar use Topsy-Turvy to reverse Croaky's maneuverability, allowing Malamar to finally hit him with Hypnosis.
Having no options left X begs Salamè to come out of his ball and fight. Not giving X the chance Malamar slams X into the ground, with Xerosic saying to destroy the Poké Ball. Despite his best attempt Salamè continues to roll out of the way, until he gets trapped by a tree root. Malamar takes a final swing but is blocked by Marisso, protecting his friend. Malamar continues his barrage of attacks when suddenly Marisso evolves into a Chesnaught. This temporary stops Malamar, but Xerosic decides its not a concern and has Malamar continue attacking. The ball finally rolls out, only for it to be revealed that Salamè has already come out, revealing he has a Mega Stone. Blue wakes up and has his Charizard reveal the same thing, and the two Fire-types begin fighting Malamar and Xerosic's four Crobat. During the fight Salamè evolves into a Charizard and the two flame Pokémon Mega Evolve, defeating Xerosic's Pokémon.
