Kamek

Kamek is an elderly Magikoopa and the main antagonist of the Yoshi's Island video game series. He acted as caretaker for Bowser during the Koopa King's childhood and served him as an advisor in later years. He has repeatedly harrassed Yoshi and the inhabitants of Yoshi's Island trying to fulfil his master's wishes.

Background
Kamek is a senior Magikoopa who wields greater magical power than others of his kind. He has faithfully served Bowser for many years, perhaps since the Koopa King's birth. During Bowser's infancy, Kamek foresaw that his young master would be challenged in the future by the Mario Bros. and attempted to remove them as an obstacle to the Koopas' conquest of the Mushroom World. The evil wizard attacked the Stork that was delivering the infant brothers to their parents in the Mushroom Kingdom, kidnapping Baby Luigi, but Baby Mario fell to Yoshi's Island below. The Yoshis would find Baby Mario and worked together to reunite him with his brother and get him home, eventually confronting Kamek and Baby Bowser in their castle. Even after turning Baby Bowser into a giant, Kamek and his young master were defeated and forced to flee.

Though Kamek failed to stop the Yoshis from saving the infant Mario Bros., he would continue to terrorize Yoshi's Island on several occasions. He would even attempt to abduct the Mario babies again and tamper with the timeline in order to stop them from thwarting Bowser in the future. All of his schemes would end in failure, of course, though he would continue to serve Bowser into his adulthood, aiding several of his master's plans to conquer the Mushroom World.

Personality
Kamek is one of the more complicated members of the Koopa Troop. He is academically-inclined, possessing great knowledge of both magic and science. He is exceptionally loyal to Bowser, having served as his caretaker during childhood and as an advisor into his adult years, and has remained obedient despite Bowser underappreciating his work and outright bullying him.

Kamek has not only acted as an advisor and general for Bowser, but has also taken on the role of mentor to Bowser Jr..

Kamek also has an effeminate side to him; he has been shown in some games to have a fondness for Princess Peach's dress and is even seen wearing it himself in Mario & Luigi: Dream Team.

Abilities
Kamek possesses all of the abilities displayed by other Magikoopas, including flight, teleportation, pyrokinesis and transmuting objects. He has also displayed a number of other abilities, such as transforming other creatures and increasing/decreasing their size, foreseeing the future, creating clones of himself, telekinesis and mind control. With his extensive knowledge of alchemy and mechanical engineering, Kamek has also manufactured various devices and magical items for his or Bowser's use.
