Kamek - Nintendo

Kamek (referred to as Magikoopa on occasion) is an old yet powerful Magikoopa, adviser to Bowser and a high-ranking member in the Koopa Troop. He is the arch-enemy of Yoshi and serves as one of the secondary antagonists in the Mario franchise, alongside Bowser Jr. He was also Bowser's primary caretaker when the Koopa King was a baby, and he continues to look after his master, even in the present day.

Overall he's very loyal to the Koopa Troop and Bowser.

Kamek is almost identical to Magikoopas; he wears a pair of round spectacles and a set of blue robes, complete with a blue wizard's hat. Both the brim of his hat and the edges of his sleeves are white. He is never seen without his scepter, which is a golden staff with a red jewel at the end; he is also usually seen with his broom, which is a stereotypical straw-colored broom with no particular quirks about its appearance. It's implied he has a shell like most koopas because of remarks like the Mario bros. "really chap [his] shell", explaining the hunch in his back.

Kamek's scales are yellow. Despite being elderly, he shows no physical signs of his age, looking very similar in the present as he did in the past.

Kamek displays powers commonly associated with Magikoopas, including teleportation, creating beings from inanimate objects, pyrokinesis, firing magical blasts from his scepter, summoning enemies and the ability to create multiple copies of himself. These are assumed to be much more powerful than those of a regular Magikoopa, because of his top rank.

Aside from the aforementioned powers inherent to all Magikoopas, Kamek is portrayed as having powers unique to himself, the most prominent of which is his ability to shrink and grow other creatures (including himself) to extreme proportions. However, he also admits that his magic is limited in some areas.

It would seem that Kamek is academic, this is reinforced by the fact that Kamek can build complicated machines. Kamek has also shown to be quite knowledgeable, quite polite and looks like he takes clear enjoyment in either conjuring obstacles for people like the Mario Bros, or serving his masters. Like Bowser and Bowser Jr. When speaking to entities like Mario and Yoshi, Kamek usually puts on a sarcastic, falsely polite demeanor.

It is hinted that Kamek has a feminine side. Like in Mario & Luigi: Dream Team when he starts talking about how cute the dress based on Princess Peach's is while calling the Magikoopa robes drab. He's capable of showing foresight and being a know-it-all. Sometimes shown by his sarcastic behavior. He can be condescending too, recorded by how he taunted Yoshis with pet names such as "baby" and "cutie".
