Bowser Jr. is Bowser's only child and the secondary antagonist of the Mario franchise. He served as the main antagonist of Super Mario Sunshine and the New Super Mario Bros. series. He is heir to the throne of the Koopa Clan.


Bowser Jr. is pretty young, he has yellow skin like his father, and small, circular eyes that are black in color. His mouth is wide, puffy and con-vexed, with a large snout, Bowser Jr. has little hands and little feet, which have small white claws, he wears a white bandana with a graffiti-design of a scary mouth, he also has a four-ribbed padded stomach and padded feet.


Bowser Jr. is a lonely child prodigy with a good heart. However, since he is an impressionable child and looks up to his dad more than anyone else, he often imitates his dad's negative behavior, misguided thinking it is the right thing to do. Due to his daddy issues, he has become somewhat of a tsundere as a coping mechanism. He is very intelligent, often inventing machines among other great technological feats. He can also be energetic and can be just as acrobatic as Mario. It is revealed that Bowser Jr. would rather be a hero from inside, but does not want to disappoint his villainous father.
