Clemont (Japanese: シトロン Citron) is a traveling companion of Ash who made his debut in Kalos, Where Dreams and Adventures Begin! along with his younger sister, Bonnie.
Clemont was said to be a genius when it came to Electric-type Pokémon. Prior to the XY series, Clemont became the Gym Leader of Lumiose Gym in order to understand Electric-type Pokémon better. However, he found that being a Gym Leader ate into his spare time and gave him little time to spend with his beloved inventions, so he created Citroid, a "Gym Leader robot", to stand in for him when he was busy. He programmed it to be tough on challengers and to reject challengers with less than four badges. This proved to be a mistake, as Citroid turned out to be violent and would shock Trainers whose challenge it rejected (or, as it later turned out, who lost to it) and eject them from the Gym. Clemont himself was deemed to be a rejected challenger as he had no badges. Clemont attempted to set Citroid to "Master Recognition mode" so he could reprogram it, but it hadn't registered the pass-code he expected it to, so he was ousted from the Gym and cut off from his Pokémon. He eventually gave up trying to reenter, as Citroid refused to allow him past the entrance.
In Kalos, Where Dreams and Adventures Begin!, Clemont was first seen some time after his ejection from the Gym with his sister Bonnie in Lumiose City. Both were standing outside the Prism Tower when they watched Ash go inside. After Citroid ejected Ash from the building for not having any Badges, Clemont saved Ash with his Clemontic Gear while Bonnie saved Ash's Pikachu. After introducing himself, Ash challenged Clemont to a battle, which he accepted. Clemont battled Ash and his Pikachu with his Bunnelby. Despite admitting that he only just caught Bunnelby, Clemont proved to be an effective battler and managed to counter many of Ash's attacks.
The battle was interrupted by Team Rocket, who were aiming at stealing Pikachu and Bunnelby. Together with Ash and a Froakie that saved Pikachu from an attack, the trio were sent blasting off. However, Froakie had gotten injured in the battle and collapsed, so Clemont suggested they hurry to Professor Sycamore's lab. Clemont lagged behind as he was forced to carry everyone's bags.
In Lumiose City Pursuit!, Clemont helped Ash stop a rampaging Garchomp by using his Clemontic Gear's Aipom Arm to break into Prism Tower. He was unable to go any further when a part of the tower collapsed in front of him and Bonnie, but Ash managed to go on and save the day.
In A Battle of Aerial Mobility!, Clemont and Bonnie officially decided to accompany Ash on his journey through Kalos. Throughout the episode, Clemont expressed his admiration of Ash and respect for him as a Trainer. Later in the episode, Clemont demonstrated another one of his inventions, a phonograph that made a sound at high frequencies to attract bird Pokémon. Unfortunately, the machine only attracted Beedrill before completely exploding. Though it caused the group trouble, Ash said that the machine was an incredible invention which made Clemont delighted and proud.
In A Shockingly Cheeky Friendship!, he and the others encountered the Dedenne they had met before. Clemont used Bunnelby to track Dedenne after it ran off so that he could keep it for Bonnie, but Dedenne had gotten lost with Pikachu. After Dedenne and Pikachu had escaped from Team Rocket and met up with the others, Dedenne fell over from exhaustion. Using one of his Clemontic Gears, Clemont recharged Dedenne despite the machine blowing up in everyone's faces immediately after. When Team Rocket attacked the group, Clemont used Dedenne to send them blasting off with Pikachu's assistance. He then caught Dedenne and gave it to Bonnie so that she could keep it in her satchel.
In A Blustery Santalune Gym Battle!, the group arrived in Santalune City, where they met the Santalune Gym leader, Viola. Clemont and Bonnie also met her sister, Alexa, who Ash already knew well from his travels in the Decolore Islands. During their tour of the Gym, Bonnie asked Viola if she would marry Clemont, embarrassing him and leading him to drag her away with his Aipom Arm. He, Bonnie and Alexa watched the battle with Viola, cheering for Ash. Just after Ash sent Fletchling out, Serena, a girl who knew Ash from her childhood, entered the Gym and joined the audience. After Ash lost the Gym Battle, they were introduced to her properly. The three later watched Ash train with Alexa.
Later on, Clemont helped Ash train with another Clemontic Gear, a cannon that fired artificial Sticky Webs, as Ash had lost the battle against Viola as a direct result of Fletchling getting stuck to a Sticky Web. Unfortunately, when he put it onto its maximum setting, it malfunctioned, got blocked by its own ammo and exploded, though this mishap did inspire Ash to use Electro Ball to prevent Pikachu from falling asleep from Vivillon's Sleep Powder. After the training was finished, he realized that Bonnie was about to fall asleep and decided to put her to bed. The next day, he, Bonnie, Serena and Alexa cheered for Ash during his rematch and victory against Viola.
In Clemont's Got a Secret!, Clemont's father, not realizing that Clemont and Bonnie hadn't told them about their ejection from the Gym, revealed to Ash and Serena that Clemont was the Gym Leader of the Lumiose City Gym in Prism Tower. Seeing that there was no point in hiding it any longer, Clemont told Ash and Serena about how he was ousted from his position by Citroid. After seeing the damage the "strange robot" was causing to the Gym and how it was driving away potential challengers, Clemont decided to challenge the robot to a battle for ownership of the gym, although he had no idea what the pass-code was. He was forced to contend with his Magnemite and Magneton, which had been ordered to patrol the Gym by Citroid, but he eventually got to the battlefield, confronted Citroid, and started its Master Recognition mode. Although Clemont finally realized what the pass-code was, he was forced to battle Heliolisk, his own Pokémon that was under Citroid's control. Clemont battled with Bunnelby and was ultimately successful in defeating Citroid, thus gaining back the title of Gym Leader. Clemont then decided to completely reprogram Citroid and left ownership of the gym to it so he could continue traveling with Ash. That night, Ash and Clemont agreed to have a Gym Battle after the former got four badges.
In Mega-Mega Meowth Madness!, Clemont befriended a Chespin from Professor Sycamore's laboratory, later rescuing it during an attack by Team Rocket in their newest mecha. Together, they deduced a way to deactivate the mecha, but when that proved unsuccessful, Clemont commanded Chespin in battle against the mecha alongside Pikachu, but their efforts were met in vain. The mecha was then defeated by a Blaziken belonging to Blaziken Mask. The following evening, Clemont decided to capture Chespin when it expressed a desire to travel along with him and the rest of the group.

Clemont is an inventor who takes pride in his inventions and science in general, although a recurring gag involves his devices failing to work (or partially working) before exploding, implying that he is currently not skilled enough to invent a long-term device, except for his air bag, Aipom Arm and the robot Citroid. He is impressed with Ash's bravery and compassion towards Pokémon, which is what motivates him to travel with Ash, so he could become stronger himself.
Clemont loves his younger sister Bonnie, being willing to catch a Pokémon for her to keep. He also takes good care of her, putting her in bed when she gets tired. However, he easily gets embarrassed by her antics of trying to get a wife for him, as seen when he visibly became upset after she asked Viola and Jessica if they could marry him, causing him to drag her away with his Aipom arm, or simply pick her up with it.
Clemont is usually shown as being nonathletic, as he easily gets tired while running. However, he also seems to have a reckless side, as shown in Giving Chase at the Rhyhorn Race! when he grabbed a rock, jumped in the air, and aggressively smashed the remote that Team Rocket were using to trap all the Rhyhorn and Pikachu in a cage.
In XY015, Clemont is shown to be a good cook, as he prepared dinner to the group.

Magnemite's known move is Thunder Shock.
