Cassius (Japanese: クロケア Crocea) is a computer technician currently residing in Camphrier Town in Kalos.

In the games

Cassius is the maintainer of the Pokémon Storage System in Kalos. He was asked by Bill to take on the role.


Camphrier Town

"Yo, how's it going there? I'm Cassius. Check this out. You know what I'm doing here? I'm keeping the PC Box running! No, seriously! Bill over in Kanto asked me to come here and run things. For real! Enough with the introductions. Get out there, catch some Pokémon, and put 'em in the PC! Yo, you got something you wanna ask me? I ain't got all day, you know?"
Boxes: "Boxes are pretty sweet. You can store up to 30 of your Pokémon in a single Box. You start out with only eight of 'em, but the more Pokémon you deposit, the more Boxes will appear! No, seriously! It's like magic! That's not all, either. You can swap whole Boxes at once if you want. For real!"
The Battle Box: "The Battle Box is no joke, yo! Got Pokémon you use in battle a lot? Put up to six of 'em in the Battle Box. Hold up--I'll explain why. See, if you're having a Link Battle over the Internet, local wireless, infrared connection, or by using the Battle Spot, you can choose to use the Pokémon in your Battle Box instead of the ones in your party. That means you don't have to go to the trouble of moving around Pokémon before a battle. It's crazy convenient! For real!"
Trays: "Trays are totally awesome, dude! They let you select a bunch of Pokémon at a time and move 'em around the PC Box. No, seriously! They're a lifesaver once you've caught a lot of Pokémon."

Cassius in Pokémon Adventures

Cassius is first seen in his cottage talking to Bill via video call about the Kalos Storage System. Bill gets annoyed by Cassius constantly ignoring his words. Cassius impatiently hangs up the call. He notes to his assistants that he hears strange noises coming from Parfum Palace, and he wants to go over and investigate. Cassius takes his assistants along to where Y, Shauna, Tierno and Clemont are, and intervenes in their battle against four Espurr by sending out his Gourgeist. Unfortunately, Gourgeist subdues the four Espurr with ease. This causes Cassius' assistants to return to his cottage. Clemont gets intrigued by what's in Espurr's ears, and tries to clip one of the Espurr by the ear using his Aipom Arm. Cassius tries to warn him, but the Espurr that was grabbed launches a beam that blasts Clemont into the sky.

Cassius takes the Vaniville quintet back to his cottage, where he learns of Y's mother's disappearance. He decides to drive the quintet to Cyllage City, where Y's mother was rumored to have been seen. On the way, he stops over at the Battle Chateau with his assistants in order to upgrade its Pokémon Storage System. Cassius also receives permission to fly the Battle Chateau's private helicopter. He explains to the Vaniville quartet that to get to Cyllage by road, one would have to go through the Connecting Cave where it is easy to be ambushed. Unfortunately, during the helicopter flight, Cassius and the Vaniville quintet are ambushed by 15 Sky Trainers. Knowing that she is to be challenged, Y, having changed back into her Sky Suit, jumps out of the helicopter to challenge them. Just moments after Y emerges victorious, one of the helicopter's propeller blades breaks off and hits Y on the head, making her fall out of the sky. Cassius, fearing that the helicopter would crash, quickly makes an emergency landing of the helicopter on Cyllage, which causes considerable damage to the city's cycle paths. After letting X view the helicopter's flying records, Cassius makes a phone call to his assistants, asking them to drive the van over. His call is interrupted by Grant who confronts Cassius over the damage to the cycle paths. While Grant and Cassius argue, X walks away and beckons Tierno, Trevor and Shauna to follow him.


This listing is of Cassius' Pokémon in the Pokémon Adventures manga.

Gourgeist was sent out to help Y, Shauna and Tierno stop the Team Flare Grunt's four Espurr. It had successfully caught three of them and afterwards, helped Cassius and the others.

None of Gourgeist's moves are known.

Debut X & Y chapter

In the TCG

Main article: Cassius (XY 115)

Cassius was introduced as a Supporter card in the Pokémon Trading Card Game during the English XY Series (the Japanese XY Era). First released in the Japanese Collection Y expansion, the Cassius card later debuted in English in the XY expansion, with both prints featuring an illustration by Masakazu Fukuda. This Trainer card allows the player to shuffle one Pokémon, and all cards attached to it, back into their deck.


  • He is the only regional computer technician not to be affirmed as having created the system they maintain.
    • According to Lumiose City residents, a more accurate representation of the PC Creator archetype may be found in the Gym Leader Clemont, who is implied and mentioned to have invented or improved upon various major gameplay mechanics, including but not limited to, Super Training and the PSS.
