Bowser Jr. is one of Bowser's children. He is the youngest of the bunch and the newest, and so far, the only one to appear in more recent games. He greatly resembles Bowser himself, only smaller, and with a bib with fangs painted on it.

Trophy Description

a bitch , who appears in Super Mario Sunshine calling Princess Peach his mother--he feels so strongly about her that he kidnaps her. Somewhat spoiled by his father, Bowser Jr. comes off as being on the selfish side. His bib is decorated with drawn-on fangs and worn like a mask--it's most likely an effort to appear more menacing.
Super Mario Sunshine, 2002
