Xerosic (Japanese: クセロシキ Xerosicy) is one of five Team Flare scientists in Pokémon X and Y.

In the core series games

Xerosic is one of five scientists that are the driving force behind Team Flare. He is also the only male scientist and has red goggles. He is first encountered in the basements of Lysandre Labs. After battling the player deep in the hideout, he offers them a chance to stop the ultimate weapon by choosing one of two buttons, as one will activate the device. However, despite both his offer and Lysandre's promise, he activates the weapon regardless if the player chooses the correct button, bragging that it is a victory for Team Flare's science.

After the downfall of Team Flare, Xerosic goes into hiding and begins conducting a project on his own, attracting Looker's attention. He sets up a lab in a secret floor of the Lysandre Labs complex and posts a notice in Lysandre Café looking for part-time employees, hiring the Lumiose Gang for security and Emma as his test subject. He creates a device called the "Expansion Suit", which can augment a human subject in a number of ways, including giving them superhuman reflexes, shapeshifting powers and the ability to hack and control Poké Balls. After teaching Emma how to be a Trainer and loaning her his Pokémon, Xerosic advances his experiment to the next stage, in which he remote-controls the suit while Emma sleeps inside, unaware of what she is actually doing. This figure, dubbed "Essentia," goes on a crime spree throughout Lumiose City using personalities and disguises based on various Trainer classes pre-loaded into the Expansion Suit's databanks.

The player and Looker ultimately unmask Essentia as Emma and discover Xerosic's secret laboratory, at which point he sets his creation on them in repeated battles. Eventually, however, Looker's dedication to Emma's well-being moves Xerosic enough to make him have a change of heart, and he frees Emma from his control. Xerosic realizes that while his creation of the Expansion Suit was a success, his plans were finished. He surrenders to Looker and is taken away for trial. Before leaving, however, he donates all of his Pokémon and the Expansion Suit to Emma, having deactivated the remote-control function of the suit, asking her to use them to protect the peace of Lumiose City.

Xerosic in the anime

In the past, Xerosic, alongside Lysandre and the other Team Flare Scientists, would help those in need, until Lysandre became disillusioned with the human race and sought to restart the world.

Xerosic debuted in From A to Z!. He was first seen at Lysandre Labs, receiving information that both Mable and Celosia had failed in their missions to capture 50% Zygarde and Zygarde Core, respectively. He then informed them that Aliana and Bryony would now take on the capturing missions as well. At the end of the episode, he was seen watching the footage Bryony had sent of her encounter with 10% Zygarde together with Lysandre. He became excited over discovering that Zygarde possessed a power Team Flare had previously been unaware of.

He reappeared in Meeting at Terminus Cave!, again coordinating Team Flare's attacks on Squishy and the study of Zygarde's powers.

In A Meeting of Two Journeys!, Xerosic traveled to a remote island with a pair of Team Flare Admins and some Team Flare Grunts. They conducted a test of a prototype weapon developed by Team Flare to utilize the energy of the Zygarde Cores and Mega Evolution. The weapon's laser, when fired, caused the trees on the island to grow wildly and begin blooming red flowers. This result pleased Xerosic, who contacted Lysandre with the news. He later continued these experiments in A Full-Strength Battle Surprise!.

Following Z2's capture in An Explosive Operation!, Xerosic was often seen monitoring Z2 and performing experiments on it, using the Giant Rock that Lysandre captured back in Mega Evolution Special III.

In Kalos League Passion with a Certain Flare!, Xerosic and several Grunts sitting in the driver's seat of a truck outside the Lumiose Gym, contacted Lysandre through a Team Flare Admin's Holo Caster. Afterwards, he was seen inside the Lumiose Gym, where he and some Team Flare Grunts set up some of their equipment that they transported from the trucks that they drove in, including glass cases that held Z2 and some Zygarde Cells.

In Down to the Fiery Finish!, he used Team Flare's Mega Evolution energy weapon to take control of Z2, causing it to unleash massive roots thorugh Lumiose City. During the crisis, Xerosic remained in the Lumiose Gym, overseeing Team Flare's operation and operating the Mega Evolution energy weapon, and eventually succeeded in controlling Squishy as well.

When Clemont and Clembot managed to infiltrate into the Gym in The Right Hero for the Right Job!, Xerosic was challenged by Clemont to a battle for the Lumiose Gym. He was also told that his machine was not an invention, since inventions should help people and Pokémon, infuriating him. During the battle, Clembot secretly began disabling the Mega Evolution ray. When Xerosic was defeated, he finally took notice of Clembot deactivating the machine. As he was running towards Clembot, however, he was sent tumbling down a trapdoor, ejecting him out of the Lumiose Gym.

In Facing the Needs of the Many!, Xerosic was planning to create Team Neo Flare. He kidnapped Clemont as an act of revenge for defeating him during the Team Flare crisis. He then used his Mega Evolution ray to take control of Clemont. Once Ash, Serena, Bonnie, and Ash's Greninja arrived, Xerosic ordered Clemont to annihilate them. However, Clemont had placed a microchip on the side of his head beforehand to prevent himself from being controlled. Outraged, he battled Ash and Clemont, but lost. He then attempted to escape by jumping out of his helicopter, but was grabbed in time by Clemont's Aipom Arm. After the helicopter landed, he was arrested by Officer Jenny.

Xerosic in Pokémon Adventures

Xerosic debuted in X-actly What They Wanted. He, Bryony, and Celosia were first seen watching the destruction of Vaniville Town caused by the battle between Xerneas and Yveltal.

In The Aegislash Agenda, Xerosic and Bryony met with Mable and Aliana at the Team Flare Secret HQ. Bryony informed the pair that their repeated failures have led to Celosia taking over their duties. In What Does Charmander Do When It Dozes, Xerosic found the dormant tree form of Xerneas on Route 8. He informed Lysandre of his discovery and asked to have the tree moved to the Secret HQ as soon as possible.

In Gathering Klefki, Clemont was held captive by Xerosic, who ordered the boy to assemble a machine he designed. Clemont initially refused, but was forced to comply after seeing his Heliolisk was held hostage. Xerosic then went to perform a check-up on Essentia's Expansion Suit.

In Quilladin Stands, Xerosic and Lysandre began draining Xerneas's life energy to fuel the ultimate weapon. They were later interrupted by X, but he was unable to defeat Lysandre despite helping Xerneas revert back to its true form. Lysandre still activated the ultimate weapon, but the combined efforts of X and his friends weakened the machine, preventing it from taking any innocent lives. Xerosic tried to capture X and his friends, but they were protected by AZ, allowing Xerneas to take everyone back to the surface. Later, Xerosic stopped Malva from using Yveltal to battle Y's newly-caught Xerxer, stating Lysandre ordered a ceasefire. Xerxer then decided to retreat, taking Y and the others with it.

In Scizor Defends, Team Flare went into hiding in the Pokémon Village. Xerosic informed Lysandre that Professor Sycamore had begun taking action against Team Flare. He suggested remaining in hiding, as Team Flare's attempt to blame the damage done by the ultimate weapon on X's group and the Gym Leaders didn't work to their expectations. In Zygarde Appears, Xerosic discovered the stones lining Route 10 were an ancient version of the absorber, allowing him to replace the one Xerneas destroyed when it revived. To his horror, Xerosic learned that Essentia's helmet had been damaged during a battle, blocking all forms of communication and control over her. He later reported the disappearance of Essentia and Zygarde to Lysandre, who ordered Xerosic to abandon the Expansion Suit project.

In Malamar Traps, X and his friends set off to confront Team Flare at the Pokémon Village. Xerosic ambushed the group and used his Malamar to put everyone to sleep. X stayed away with Y's Croaky's help, but couldn't beat Xerosic as he was using a Pokémon that wasn't his. After the others woke up, X and Blue stayed behind to face Xerosic while the others went ahead. With X's Salamè and Blue's Charizard, they easily defeated Xerosic with the power of Mega Charizard X and Y, respectively.


On hand

Inkay → Malamar
Malamar is Xerosic's first known Pokémon, which he had ever since he was an Inkay. He was first seen watching Xerneas and Yveltal's rampage from the outskirts of Vaniville Town. Later, he was used to capture AZ at the Team Flare Secret HQ. Near the Pokémon Village, Xerosic used Malamar to attack X and his friends. By using Hypnosis, Malamar put everyone to sleep with the exception of Croaky, who used his tongue to block out the sound, and X, whose ears were filled with water. Together, X and Croaky knocked Malamar down, but he quickly got back up and defeated Croaky.

Malamar's known moves are Hypnosis, Topsy-Turvy, and Night Slash, and his Ability is Contrary.
