Kamek (Earth-1344)

"Welcome! It's time to face my magic!"

- Kamek

Kamek is an old, yet Koopa and advisor to Bowser, and the arch-enemy of Yoshi. He serves as one of the secondary antagonists in the Mario franchise, alongside Bowser Jr.. He was also Bowser's primary caretaker as a child.

Personality
Kamek is academic, as the board that he owns is a library. Kamek is shown to be quite knowledgeable, since he gives articulate advice. Kamek is also shown to be quite polite, though he takes clear enjoyment in either conjuring Bad Luck Spaces or scorceling them into Extra Bad Luck Spaces.

He acted as a mentor to Bowser Jr., and is very loyal to the Koopa Troop, even making Bowser Jr. swear to aid the minions beyond the sake of personal glory. He is also shown to be very concerned when the Koopalings begin slowly dwindling in numbers.
