This Magneton is one of Clemont's Pokémon who is living in the Lumiose City Gym.
Magneton is another of Clemont's Pokémon who served as a patrol to the Gym while Clembot was in control of it. After attacking the group with Metal Sound, Fennekin battled it. It easily dodged Fennekin's Ember by temporarily separating itself into three Magnemite but was stopped by Froakie's Frubbles.
When Clemont returned to Lumiose City to train for his gym battle against Ash, Magneton was used in a practice battle against Clemont's Bunnelby, which lost after Bunnelby mastered a mysterious new move.

Unlike most Magneton in the series, Clemont's Magneton appears to have the ability to split into three Magnemites while battling. This ability was shown in manga in Victim of Venusaur, where Lt. Surge's Magneton splits into three Magnemite to save him from falling.
