|Class:||Team Plasma Boss|
|First Appearance:||Black 2 and White 2|
Colress is a boss of Team Plasma, debuting in Black 2 and White 2. He researches Pokémon strength and is experimenting on something to do with the dormant abilities of Pokémon. He is said to be mysterious and difficult to read.
Colress is a man with blonde hair and wears a blue stripe around his head. Colress has yellow eyes and wears glasses. He wears a long white lab coat, a pair of white gloves and a black uniform with blue outlines. Colress also wears black shoes.
Colress is a scientist who aims to unlock the full potential of Pokémon, regardless of the cost. For this reason, he chooses to side with Team Plasma and assist them with their plans as long as his research remains unimpeded. Despite his allegiances, Colress openly disagrees with Plasma's ideologies and greatly dislikes Ghetsis, though his opinions on the other Sages is unknown. Throughout the games, Colress is depicted as genuinely helpful and friendly, regarding the player as a worthy opponent and acquaintance. He is excitable and passionate about his research and battling, and will repeatedly ask the player for rematches if visited during the postgame.
Black 2 and White 2
Colress is first encountered in the Castelia Sewers after defeating two Team Plasma grunts. He is met again on the northern part of the city. He explains to the player that he disagrees with the old Team Plasma's ambitions to liberate Pokémon from the grasps of humans. He is instantly encountered again on Route 4. He helps the player proceed by moving a group of Crustle that were blocking the path. He then challenges the player to a battle for the first time.
After the player fights his/her way through the Plasma Frigate, Colress is encountered again in his chamber on the ship. Much to the player's disbelief, Colress reveals that he sided with Team Neo Plasma to help with his research on bringing forth the full power of Pokémon. He then challenges the player to another battle. When he is defeated, he applauds the player's determination and allows entrance to Ghetsis's quarters on the ship.
When the player enters Ghetsis's chamber, he reveals that Colress is the boss of Team Plasma. He rants about his defeat.
Colress remains on the Plasma Frigate even after the player defeats the Elite Four and the Champion. He can be rebattled once per day, and he will give the player a Master Ball after the first rematch. After he is rebattled the first time, he can be found on the helm of the frigate.

Colress is a boss for Team Plasma and conducted experiments with wild Pokémon in an attempt to bring out their true strength. From his base in an abandoned observatory outside of Floccesy Town, he used a large machine to generate EM waves that resonated with small devices on the wild Pokémon's foreheads, increasing their aggression and attack power while also rendering them subservient to Team Plasma's commands.

- Colress always appears as the final opponent in the first Driftveil Tournament visit, as the opponents fought are scripted to win, with Hugh being the first trainer, and Cheren being the second.
- Colress lacks a VS sprite the first two times he is fought. When he is fought as the Boss of Team Neo Plasma, he uses the template that N and Ghetsis use when they are battled, and his VS sprite is there. When he is rebattled in the Post-Game, he uses the template used by Hugh.
- His name may be a pun on callous, which is to be uncaring and focused.
