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.
He is a very keen inventor, but there is a running joke involving his devices exploding instantly, or working briefly, as seen in the anime. He is also dedicated to science and only fears something if it defies logic. Clemont is also shown to have fear of standing in front of the camera, which would mean he has photophobia.
One of Clemont's most noticable traits is his care and responsability over Bonnie. He gets upset and even angry when she wanders off or gets into trouble, and often comes across as nagging. Still, he is very affectionate towards her, hugging her when she is afraid or holding her hand, and aware of her physical needs, as shown when he makes her eat her vegetables, even though she doesn't like them. He is very protective of her, and puts her safety above all else, even risking his own life to do so on occasion.
Clemont is the Gym Leader of Lumiose City. When he first met Ash he had a battle with him. For a time during their travels together Ash was unaware of the fact he was the Gym Leader. When Ash and Serena found out, he told them about how one of his inventions got hold of his Gym after it went online. With Ash's help he managed to bring it back under control and get his Gym back.
Clemont used to play with a Shinx when he was little. It was the Shinx's need for a place to recharge that inspired Clemont to come up with his Clemontic Shower idea for his graduation research. After he unveiled it, he went to meet with Shinx at their usual meeting place to celebrate with cake. But the town mayor arrived and took Clemont to another party before he could get there. By the time he got to their meeting place Shinx had gone, believing him to have abandoned it. Years later, Clemont re-encountered Shinx who had since then evolved into Luxio. He could tell Luxio still harbored resentment for him never showing up years ago. When the gang confronted Team Rocket to try and get back the town's electricity Clemont took a hit for Luxio, who realized that Clemont still cared for it. Clemont told Luxio why he hadn't shown up that day in hopes that it would forgive him. It didn't seem to right away, but come tomorrow when the gang arrived and Clemont and Luxio's old meeting place, Luxio was there, reading to give Clemont a second chance. Overjoyed at having his old friend back, Clemont tossed a Poké Ball at Luxio, who allowed itself to be caught.
Much later, when the gang stopped for lunch while traversing the Lumiose Badlands, Clemont was lost in thought for a while over whether or not he had progressed enough in his journey. Remembering past examples of Ash's fortitude, he wondered if he would be able to give him a proper battle as a Gym Leader. Because he was so lost in thought, the gang ended up eating burning pancakes. When the gang got walking again, they happened upon the Kalos Power Plant, which Bonnie told Ash and Serena Clemont had designed. Clemont shyly corrected her, saying he only programmed it. As they went to check it out, Pikachu, Luxio and Dedenne fell under the control of the radio waves emanating from the antenna which no longer pointed upwards toward outer space. The gang tried to stop the Pokémon, but they turned on them and launched a collective electric shock. The gang later discovered an entire horde of Electric-type Pokémon sharing the same red eyes as Pikachu, Dedenne and Luxio. The group of Electric-types entered the Power Plant. Remembering the plant's blueprints, Clemont led the rest of the gang to a shaft they could enter through. Ash's Frogadier clogged the blades with its Frubbles and they made their way inside, untying a trio of plant workers who told them they'd offered food and shelter to a band of travelers who turned on and captured them. The gang agreed to stop the trio, entering the control room where the Electric-types were gathered. The trio was none other than Team Rocket, who in order to stop the twerps from foiling their plans, drained Lumiose City's entire power grid, effectively leaving people stranded and helpless and holding the entire city hostage. They also had Pikachu and Luxio attack Ash and Clemont, who promised to ease the suffering Luxio was going through. He activated his Clemontic Gear and redirected Luxio's Discharge to the floor when the central ring turned red, overloading the system and shutting it down. He collapsed onto Luxio who immediately starting glowing and grew over twice its size into Luxray. When Team Rocket tried to retake control of the Electric Pokémon, Luxray revealed its new move Electric Terrain, which powered up Electric-type moves. Using the boost this provided, the Electric-types launched a collective electric shock on Team Rocket, blasting the trio off yet again. After the whole ordeal was over, Clemont asked the workmen to take him back to Lumiose City with them. The gang was surprised. He turned around and explained he wanted some time to reflect and train so he could give Ash a proper Gym battle. He placed Bonnie in Serena's care and boarded the chopper with Luxray, which took him home.
Over the course of the next two episodes, Clemont was seen at the very beginning, congratulating Bunnelby on learning a new move, and at the end when he finished inputting Ash's battle style data into Clembot. The robot however couldn't comprehend the information and promptly blew a circuit, leaving Clemont with a burnt afro.
'''Clemontic Gear''' (Japanese: シトロニクギア,Citronic Gear) are the inventions created by Clemont in order to accomplish various kinds of tasks. Most of his inventions are stored inside his Bag.
But as a running gag, most of his new devices ends up exploding for various reasons (mostly relating to them going over-their-limit) which leads to the group facing the aftermath of the explosions.
Usage: It is a standard invention stored inside his bag and is useful in order to protect people.
Status: It is present in working condition.
Usage: A useful invention attached at the back of his bag. It mainly act as a third arm for Clemont (just like a Aipom's tail acts as a third arm, and hence the name). This arm has considerable functionalities, like capable of unlocking security door access and is also quite powerful as its easily able to lift standard size boulders and has enough power to pull a person away.
Status: It is present in working condition.
Bird Pokemon Luring Machine
Usage: The basic concept of this machine was to attract various kind of Bird Pokemons by stimulating the magnetic substance that control their homing instinct using sound waves of certain frequency to draw them closer or repel them away.
Status: The machine failed to attract Bird Pokemons, but instead worked on the horde of wild Beedrill that where in the forest and attracted them instead. Thinking that the frequency created by the machine was wrong, Clemont tried to use the machine on an higher frequency in hopes of attracting Bird Pokemon, which caused the machine to exploded due to an overload.
Electricity Generating Machine
Usage: The concept of this machine is to utilize the Frictional Energy and transforming it into Electrical Energy, thus generating Static Electricity.
Status: It was used to help Dedenne recover its strength but during its activation, Clemont accidentally broke its Control Lever and thus couldn't control the machine anymore which ended-up exploding because of a overload.
Sticky Never Never Give Up Machine (Called the "Sticky Web Sticky Wicked Whacker Wonk" in the dub)
Usage: This machine breaks down the composition of Sticky Web on a DNA level and is able to perfectly reconstruct its stickiness, colour, smell and nutrients and fire at its target. According to Clemont, he had applied for a "Patent Application" for this machine to relevant authorities.
Status: This machine was created in order to help train Ash for his re-match against Viola, and it was really useful to Ash. But when Clemont decided to use it in Max Level, a misfire causes the mouth of the machine to clog up with the Sticky Web composition and with its outlet blocked, the machine ended up exploding.
Bunnelby first appeared in Kalos, Where Dreams and Adventures Begin! where it was used by Clemont in his battle against Ash and Pikachu. Bunnelby was shown to be a strong battler, easily dominating the first part of the battle until it made the mistake of clamping Pikachu's tail with its ears. It knows Dig, Mud Shot, Double Slap and Double Team.
Chespin first appeared in A Battle of Aerial Mobility! under the ownership of Professor Sycamore as a Starter Pokémon for new trainers. It has been shown to be a gluttonous Pokémon. It knows Pin Missile, Tackle and Vine Whip.
Clemont knew Luxio from the time he was a Shinx and had been friends ever since. However, when Clemont was forced to leave for a ceremonial dinner on the day of his graduation, Shinx was left all alone. He later reunited with Clemont and during his absence, he evolved into a Luxio. Since Clemont's absence, he lost his trust towards him and believed that Clemont abandoned him. However, after Clemont defended him from Team Rocket, Luxio regained his trust and decided to travel with him from now on. During a battle against Team Rocket at the Kalos Power Plant, it evolved into Luxray. It knows Swift, Thunder Fang, Discharge, Wild Charge, and Electric Terrain.
Magnemite is Clemont's Pokémon who served as a patrol to the Gym while the Clembot was in control of it. After Clemont greeted it upon his return, it pretended to be happy but then attacked him with Thunder Shock. It continued attacking until Froakie's Frubbles put a stop to it.
Magneton is another of Clemont's Pokémon who served as a patrol to the Gym while the 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 Ash and the others were kidnapped by the three evil Malamar who plot to destroy the world, Clemont, along with James, temporarily used a group of Malamar who are good and gentle in a desperate attempt to rescue everyone from danger. Their moves are Psycho Cut, Psychic, and Hidden Power.
When Ash and the others were kidnapped by the three evil Malamar who plot to destroy the world, Clemont, along with James, temporarily used a group of Inkay in a desperate attempt to rescue everyone from danger. Their only move was Flamethrower.
Clemont takes on the role of the traveling older sibling, but this time, as the older brother with his little sister, Bonnie. In Pokémon: Advanced Generation, May was the first older sibling with her younger brother, Max.
Clemont is also the third Gym Leader to travel with Ash, with Brock and Cilan being the first two. However, regarding characters that have something to do with the title Gym Leader at all, whether as a former or future holder of the position, then Clemont is the fourth character to do so, with him, Brock and Cilan each being moved up a spot as Misty was the first Gym Leader to travel with Ash, though her case is as a future Gym Leader.
Still Clemont is the third male Gym Leader.
Clemont appears to be the same age and height as Ash, as the previous male traveling companions were both taller and older than him.
Whenever Clemont reveals any of his new gear or inventions, Ash takes an extreme liking and awe to them, while Serena and Bonnie dislike the names that he comes up with for them.
