Bowser Jr. is Bowser’s son. He can be summed up as a bold and energetic troublemaker. He is also bratty, spoiled, and short tempered, though sometimes, there have been statements that he has a lonely side. His favorite hobbies are stealing cookies, causing trouble for people, and scribbling. However, he seems determined to defeat Mario in a fair fight in order to prove his power.He is also occasionally lazy due to riding his Junior Clown Car, but he’s also apparently quite bright since he is brainier than his father. Bowser Jr. follows Ganondorf’s orders due to Bowser collaborating with the King of Evil, but he is actually rebellious towards Ganondorf, since he has a sneaky side and he wants to show that he has the power to defeat a greater evil to make his father proud.

Like with Ness, it doesn't matter if you're male or female, you can audition for him.Try to sound as he does in the Mario games he's appeared in. Give him a childish personality and a medium-high pitch voice.
