Bowser Junior

Bowser "B" Koopa Junior Montgomery Hugh Brat II, 

or simply known as, Bowser Junior or Lil Koopa, is a minor

character that has only appeared in a small set of videos

and is sometimes extremely hard to find. He is the spoiled

bratty son of Bowser and treats his elders badly.

His favorite place to visit is Nickel City, and got his babysitter,

Waluigi kicked out, after he got abused. Not much is known

about Junior except that he likes to hang out with his friends

Phillip, Craig, and Bili The Goomba, and gets into trouble and

mischief.
