Bowser Jr. (クッパ Jr., Koopa Jr.) is a playable character in Super Smash Bros. for Nintendo Switch. After initially being leaked on August 19th, 2014 as part of the ESRB leak, he was officially revealed during the Super Smash Bros. for Wii U 50-Fact Extravaganza on October 23rd, 2014. Caety Sagoian reprises her role as Bowser Jr.'s voice actor, albeit via recycled voice clips from various Mario spin-off games. The Koopalings also use their voice clips from the New Super Mario Bros. games, which were voiced by Lani Minella (Larry, Morton, Wendy, and Lemmy), Mike Vaughn (Iggy and Ludwig) and Dan Falcone (Roy).
Bowser's beloved, spoiled son sports a bandanna with a large mouth drawn on it. Like his father, Bowser Jr. longs to take Mario down. In Smash Bros., he'll fight from inside his heavily armed Junior Clown Car. The Clown Car takes less damage than Bowser Jr., so mind your positioning.
- Bowser Jr. is the only character who does not have an alternate costume that shares the same name as the default costume or is a palette swap of the original costume. Due to this, he's the only character to use his default color scheme in his Alt. trophies.
- Similarly, Bowser Jr. is the only character who does not use an alternative costume when he is fought in rounds 4-5 in Super Smash Bros. for Wii U's classic mode, as well as Smash Tour with customs. However, Larry will appear in his place in a team battle if the player chooses a previously-defeated Bowser Jr. as a teammate.
- This additionally makes Bowser Jr. and Villager are the only characters where all eight of their palette swaps have a chance of appearing in All-Star Mode. However, because his placement in All-Star Mode is based on his debut rather than that of the Koopalings (who debuted before him), the Koopalings will be misplaced chronologically during All-Star mode if the opponent's costume is a Koopaling. The same applies to Olimar and Alph.
- In Bowser Jr.'s reveal trailer, he is seen firing a cannonball which then explodes. However, this does not happen in game, not even from his custom moves.
- Bowser Jr. is the only newcomer to be both a starter character and an unlockable character in SSB4.
- Bowser Jr. was on the brink of being cut as a playable character due to limited time and resources. He barely got onto the roster due to the game staff's diligent work.
- When Bowser Jr. gets a Super Leaf, the ears will be on his head but the tail will be on the back of his Junior Clown Car.
- When he uses Abandon Ship!, the tail on the Junior Clown Car disappears.
- One of Bowser Jr.'s conquest teams is called the "Kooky Kids". "Kooky" is also Ludwig's name in the DiC Entertainment cartoons The Adventures of Super Mario Bros. 3 and Super Mario World.
- On the official Super Smash Bros. Facebook page, Wendy was called "a Kootie-Pie", a reference to her name in the DIC Entertainment cartoons.
- On the same Facebook page, Lemmy is noted as "Hip but no Hop", a reference to Lemmy being called Hip and Iggy being called Hop in the cartoons.
- In Mario Kart 8 Deluxe, the Koopa Clown Car vehicle, if used by a Koopaling will change colors to match the ones they use in Super Smash Bros. 4.
- Bowser Jr., along with Bowser, Yoshi, Wario, Mr. Game & Watch, Little Mac, Young Link, Ganondorf, Corrin, Charizard, Lucario, Mewtwo, Pac-Man, Sonic, Justice and SpongeBob are the only characters who transform during their Final Smash. Inkling, Goku and Sakura transform from one of their special moves.
