Clemont (Japanese: シトロン Citron) is the Gym Leader of Lumiose City and one of Ash's companions.
Clemont is the Gym Leader of Luminose City and, when he originally meets Ash, he battles him after he was kicked out of the Lumiose Gym, with Ash unaware of the fact he is the Gym Leader. He is an avid inventor and has a device called the Aipom Arm in his backpack. He has a little sister named Bonnie. He also appears to not be very physically fit, as he runs slower and arrived at Professor Sycamore's lab moments after Ash and Bonnie. It was revealed that one of his inventions got hold of his Gym after it went online.
He is a boy with blonde hair, blues eyes and glasses. He wears a blue jump suit with yellow strips on the legs. He also wears black shoes and has a device on his back in which he uses to perform different actions.
