Description
Ghetsis, leader of Team Plasma, possesses red eyes and long pale green hair, often obscured on the right side by a distinctive red eyepiece. He conceals his right hand within black robes featuring an eye pattern and wears yellow bracelets on his left forearm with black boots. His primary accessory is a cane bearing the Team Plasma logo.

Driven by a cold, power-hungry nature, Ghetsis prioritizes control over Unova. He manipulates his adopted children, particularly N, promising N would become Team Plasma's king to liberate Pokémon. This deception exploits N's ability to communicate with Pokémon, forming Ghetsis's core strategy. He heavily relies on scientist Colress, utilizing his technology to control the legendary Reshiram for destructive purposes.

Ghetsis raised N from childhood as Team Plasma's heir, advancing the Pokémon liberation goal. His plan involved manipulating N into summoning Reshiram during a coronation. When this failed and Reshiram destroyed Team Plasma's castle with Fusion Flare, Ghetsis recalibrated his approach.

In the anime, Ghetsis monitored Colress's development of Pokémon-control technology. Upon intruders breaching Colress's laboratory, he authorized Beartic to intercept them. Later, he mobilized Team Plasma grunts to locate the vanished N, though N was rescued by two unidentified girls. Ghetsis dismissed Colress's inquiry about capturing N, demanding obedience while permitting Colress to continue experiments aligned with Team Plasma's objectives.

After Team Rocket escaped the laboratory, Ghetsis redirected efforts toward securing the Light Stone from Reshiram's resting place, the White Ruins. Confirming both N and the Light Stone were secured, Ghetsis traveled to the ruins. He took possession of the Light Stone from N and performed a ritual with staff gestures and chants, summoning red glyphs that transformed the stone into Reshiram.

Ghetsis commanded the mind-controlled Reshiram to attack opponents, including Ash and his allies. When Ash's Pikachu resisted Colress's control technology, Ghetsis ordered intensified suppression efforts. Reshiram eventually broke free, destroying Colress's machine and aircraft. During the retreat, Ghetsis and his commanders were immobilized by combined Ice Beam, Rock Slide, and Stone Edge attacks from Dragonite, Crustle, and Krokorok. Authorities subsequently arrested him.
