A day with Bowser Jr. Wiki

"(at Bowser Jr.) Right now, you were struck by luck. But I warn you, my brother! Sleep with one eye open from now on, because I'll make you regret the day you were born! The same day you stole my precious throne! I'll make you pay! So says...Ludwig...Von--(is interrupted by Bowser)" - Ludwig

Prince Ludwig von Koopa is the secondary antagonist of A day with Bowser Jr and it's sequel, Living with Nerdy, the main antagonist of Two Koopas for a Throne, and the deuteragonist of Rise of Fawful. He is the oldest member of the Koopa family, and the leader of the Koopalings. Prior to Bowser Jr's birth, he thought he was the heir to the Koopa throne.

He is voiced by The Guy.


Nothing much is known about Ludwig's history, except that he was considered the heir to the Koopa throne, until Bowser Jr was born and for an unknown reason "stole" the heirship the same day. This event is what caused his open grudge against Bowser Jr. He is the eldest son of Morton Koopa Sr.


Ludwig has a very dark personality, both aggressive and vengeful (something he is aware of, as seen in Rise of Fawful). He is very determined and will not stop at anything to get his goals (such as attempting to murder Bowser Jr. to merely get back his heirship to the Koopa throne, or initially working with Fawful under the presumption he would be king of the Koopa Empire after Bowser was turned into a baby.) His desire for power goes beyond his care for his family. At the end of Rise of Fawful, Ludwig and Bowser Jr. got along, and Ludwig even saved Bowser Jr.’s life.


Ludwig is very strong, and is able to win a fight with Junior very easily. However, he still can be easily overpowered by very strong people like Bowser. He is very skilled at hand to hand combat, as his punches are so powerful that they can make people fly meters away and break concrete. He is also very skilled at attacking with his shell, as he can fly in it, travel at high speeds in it and cause serious damage by hitting something or someone with it. He may also appear equipped with his Magic Scepter, which is able to create blue fiery blasts, which are capable of breaking walls.


Outside of his normal life which seems to revolve around his hate for Bowser Jr, Ludwig has a passion for playing the piano, and composes songs on it too, like "Junior will die".


  • His relationship with the other Koopalings is unknown, but they likely respect him, as he is their leader.
  • He no longer has a hatred for Bowser Jr after the events of Rise of Fawful.
    • In part 3, he possibly breaks the fourth wall by saying "What? I'm the dark and edgy character here?!".
    • Ludwig is the only Koopaling to have a major impact on the series other than Iggy and Lemmy.
  • Ludwig's hair changing to blonde in Two Koopas for a Throne is a reference to Super Mario World, where his sprite is depicted of yellow hair.
