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

In the games

Xerosic is second-in-command of Team Flare and one of five scientists that are the driving force behind the team. He is the only male Team Flare 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 turn off the device and the other will activate it. However, despite both his offer and Lysandre's promise, he activates the weapon regardless of the player's choice, 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. Realizing that while his creation of the Expansion Suit was a success, his plans are finished, and Xerosic 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.

Lysandre Labs (initial visit)
  • Before battle
"So the Poké Balls we received and the Pokémon we've gathered are where they need to be. Add it all up, and it means all preparations are complete!"
"Oh ho ho! You're the one I've heard so much about! I've been waiting for you! I need to do a little research on you! Come, let us begin!"
  • Being defeated
"Oh ho ho! You're wonderful! Your Pokémon are amazing!"
  • After being defeated
"Wonderful! Amazing! You have tremendous skill and bravery! When you add that up, it means I will tell you something very interesting. It happened 3,000 years ago. The ultimate weapon was used to put an end to the war in an instant. If we use that incredible power, we can finally free Kalos of the foolish humans that plague it! Behind me you'll find a red button and a blue button. One of them is the button for activating the ultimate weapon. Push one now! Come on! Push one!"
Red button: "You pushed it! Oh ho ho! You pushed the little red button! Too bad...for you! Pushing that button has enabled us to use the ultimate weapon! Don't feel too down, though. I would have activated it even if you had guessed correctly.
Blue button: "You pressed it! Oh ho ho! You pressed the blue switch! Winner, winner! Congratulations! But I'm still going to activate the ultimate weapon! I know the boss promised that we wouldn't if you pushed the correct button, but I refuse to let the potential go to waste! I'll just use my remote, here! Click-click! And the power is ON!
Either way: Come on! Look! Look at the monitor!"
  • If talked to before pushing the button
"I'm very curious to see the results of my research. To use the ultimate weapon to cleanse this world once and for all... It's fascinating!"
  • After pushing the button
"Did you see? The ultimate weapon is reborn! The poisonous flower has bloomed! All shall perish! Except for Team Flare! Look at Geosenge! It has bloomed in Geosenge Town! The boss's dream of creating a beautiful world will come true! Add it all up, and it equals... a victory for our SCIENCE!"
Lysandre Labs (post-game)
  • Chapter 5
"Hmm... Why did the remote control malfunction only that one time? Do I need to do more than simply put her in a state of sleep? Must I subdue her spirit, too? No, no. Doing that would put far too great a strain upon Emma's mind..."
"Oho ho ho! You're the boy/girl from the glitched trial! You've been interfering with my research! Very well. You will be the subject for my next trials! If Essentia can defeat you in the Expansion Suit, that is all the proof necessary to show that my research has been correct from the start! Come, Essentia!"
"Now, battle! Battle, my Essentia!"
  • After the first battle with Essentia
"Astonishing! More than satisfactory! But Essentia's skills go far beyond this! Now, battle! Battle on, my Essentia!"
  • After the second battle with Essentia
"Wonderful! Magnificent! But Essential is only getting started! Now battle! Battle on, my Essentia!"
  • After the third battle with Essentia
"Come, come, we can still go on! Or are you worn out? Too bad that Essentia will never experience physical or mental fatigue as long as she wears the Expansion Suit that I designed! Now, battle! Battle on, my Essentia!"
"What?! Who are you two? Why are you here?"
"You can't just barge into a private residence like this! This is a crime!"
"Grrr... Still, you will not capture me! Go, Essentia! Get them all!"
"It's useless, you fools! Nothing you try will work! Emma cannot hear you! The one in control of Essentia is not Emma, but me!"
"Isn't the power of science amazing? There's no way she will hear you now!"
"What?! How can this be happening? Not a problem, though. Watch this! Remote-control function... Set to maximum output!"
  • After the final battle with Essentia
"... ... ..."
"... ... ..."
"Remote control... Power down. Deactivate."
"All I did was turn off the remote-control capability. There was never any danger to the girl."
"Yes, my girl... We're done... You did a good job, Emma. The trials are now complete. I'm afraid your job is all over."
"Of course. Why would I mind having a chat with you..."Looker," or so you're apparently called."
Looker Bureau
"Oho. Right enough. The graffiti in the art museum and the theft of the Trainers' Poké Balls? All me, controlling Essentia remotely with the Expansion Suit! Emma was clinically unconscious in the suit. Her mind had no clue what her body was doing. She has zero responsibility for any of the crimes. You need not doubt her."
"If you're apprehending anyone, it should be me alone."
"You had better believe it. Emma is a fine person. She may be a bit foolish, but she's strong and clear in purpose. Yes, clarity... It is required when one dedicates oneself to a single pursuit. Clarity of heart and purpose is needed if work such as my research is to succeed. The Expansion Suit that I dreamed of could only have been created thanks to the clear dedication of that girl's heart. When you add that all up, it means... That I have no regrets. Take me away, Officer."
"... ... ..."
"... ... ... ... ... ... Looker--or whatever your name truly is--your soft words are unexpected... But not unappreciated. Th-thanks."
Lysandre Café
  • Final Chapter
"I'm telling you I gave them back! Every last one of them!"
"And I did! I returned them! And I'm turning myself in without a fight, so just give me a minute!"
"Haha! Here they come!"
"Because I contacted Emma, of course! I'm sure she'll be here any minute, too!"
"Good timing, Emma!"
"Yes! That is it! Bonds! The preposterous notion which cannot be seen nor measured! And yet I cannot deny that they do still exist! Fear not, Emma, for I suspect that you will always be tied to the International Police by your bonds!"
"Emma! I give you my Expansion Suit! I have removed the remote-control functionality, so you needn't worry! As the new head detective in town, please use your powers as Essentia to protect your beloved Lumiose City! And...and... Please take all of the Pokémon that I raised for so long! They are yours now!"
"Emma! Don't you mess this up, my girl!"
