Koopas are evolved turtles and Bowser’s assistants. The koopa can be of different colors, if it has a green shell, it does not stop at the edge of a platform or precipice. A difference between the goombas and the Koopas is that in case of koopas, Mario has to jump twice to finish them, once walked on four legs but now they are seen on two legs wearing shoes in opposing thumbs. There are also koopas with wings called Koopas Paratroopas, although in the classic games of Mario, they only jumped, in the most modern games, they are seen flying without touching the ground at any time. Their leaders are Koa Koa (King Goomba) and Bowser (King Koopa).

Morton Jr. Koopa
It is the sixth of koopaling brothers. He has a star-shaped scar on his face, since when he was small, a star hit him and left a mark. Although he is the largest in size, he is not more powerful than his other brothers.
Seventh in the kooplings, it is a clever Koopa that throws hammers. Bowser is said to have more confidence in them than any other Koopa.
