Bowser Jr. is a veteran fighter in Super Smash Bros. 5. Similar to his portrayal in Super Smash Bros. for 3DS/Wii U, he uses his Koopa Clown Car to fight, and stays inside of it almost all of the time. He is one of the few characters with alternative costumes.

Anyone caught in the "X"'s hitbox will take damage. The "X" will clear away with a final burst after some time.
