Bowser Jr. or Bowser Junior is Bowser's winning-cool son and an ally of SMG4. He is normally a friend of him and Mario but in some cases he's an anti-hero or a minor villain. He is also friends with Henry and Samantha. He hates Phillip and Kelly Bomb and helps SMG4 defeat them. Also, he normally stops trying to beat his allies after a certain number of defeats (mainly in the Super Mario Galaxy longplays). He really likes swag and hates the book Chinese Cinderella due to one of the lines in the book. He sometimes wears a pair of swag sunglasses.
