Bowser Jr

Bowser Jr. is an antagonist in the Mario series. He is Bowser's son and one of Mario's biggest enemies. He frequently makes attempts to capture Princess Peach though Mario always manages to rescue her..

Physical Appearance
Bowser Jr. shares many physical similarities with his father, but he has a red ponytail as opposed to Bowser's spiked hair, small black beady eyes, a more rounded snout, and a single sharp tooth visible in his overbite—features which, along with his body shape, make him look almost identical to Bowser himself at a younger age. He often wears a bandanna. In Super Mario Sunshine, it was originally blue with a messy drawing of Mario's distinctive nose and mustache, but that was later replaced with a white one with a mouth and sharp teeth drawn on it, which he puts over his real mouth to look more intimidating.
