Mantle



Mantle is the main antagonist of the Pokémon anime episode called ''Rotom's Wish. ''

History
Ten years ago, Mantle and visited the Lost Hotel with his gang of crooks on it's opening day and forced the owner, Weston, to have a Pokémon battle with him, on the condition that he would gain ownership of the hotel if he won. Weston's Pokémon, Rotom, was scared of Mantle's Krookodile and fled into an air vent. Mantle claimed to have won by default as a result and claimed ownership of the Lost Hotel. He made Weston the counter clerk of the hotel and began challenging visitors to battles on the hotel's battlefield, taking their Pokémon after beating them. The Hotel fell into a decayed state under his ownership.

Ten years later, Ash and his friends came to visit the hotel while Mantle was having a battle against a visitor. Angry at Mantle for taking Pokémon from others, he confronted him. Mantle challenged Ash to a battle in response, on the condition that he would claim Ash's Pikachu if he won. But before the battle started, Weston's Rotom came out of a trash can and led Ash and his friends away. Rotom revealed to them what Mantle had done ten years ago and sent them back in time to undo his actions.

During the battle between Mantle and Weston in the past, Ash interfered when Mantle claimed to have won by default. Mantle gave him and his friends five minutes to find Rotom and get him back to battle against his Krookodile. They managed to find it, and Weston made Mantle swear to never steal Pokémon again if he lost. Rotom appeared to get scared again during the battle and went into the air vent again, but it actually went into multiple appliances that were in the hotel's storage room to change into different forms and have a type advantage over Krookodile.

In the end, Rotom successfully defeated Krookodile, but Mantle refused to accept the loss and went back on his promise, but he surrendered after being shocked by both Rotom and Pikachu, changing the past and allowing Weston to remain the owner of the Lost Hotel. Afterwards, Rotom brought Ash and his friends to a changed future, where Mantle and his henchmen had reformed and become employees of the Lost Hotel.
