Clemont (Japanese: シトロン Shitoron) is a Pokémon trainer of the Kalos region and one of Ash's travelling 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. Later, one of his inventions gets hold of his Gym.
