Bowser (Born 1962) is Mario's archenemy. He is known for his countless attempts to kidnap Peach Toadstool, but every attempt failed. He is the leader of an army (and a "family"). He is the king of Koopaland from 1998-present, the king of Dark Land from 2009-present and the king of Bowser Land from 2018-present.


Bowser was born in 1969 as the 1st and eldest son of King Morton Koopa Sr. His mother was Bowserina. His babysitter was the old magikoopa Kamek. As a kid, Bowser was very bratty and mean because he was spoiled rotten by his parents and Kamek.
Kamek had a vision one night in 1971 that two babies will cause future disaster to the Koopas. When the stork was delivering them from Star Haven—the mystical land where star children come from—to their adoptive parents Kamek kidnapped the Stork and Baby Luigi. Baby Mario fell into the hands of the Yoshis, starting what we all know as the adventure in Yoshi's Island. Baby Bowser got deafeated by Green Yoshi in the end, causing Bowser and Kamek to hold a grudge against the Yoshi Tribe.
Years later, Bowser tried to get revenge on the Yoshi's by stealing the Super Happy Tree. The Yoshi Tribe again defeated him. 20 years later, Bowser tried to get revenge again in which we know as the Tetris Attack.


Bowser's paternal grandfather, the unnamed King of Koopaland died in 1999 and Bowser became the king. He decided to conquer Brooklyn and conquer and and turn the world into his own image. The Mario bros went to Muda Island to stop the Koopa Empire from reaching Brooklyn, foil Bowser's attempts, and send him back to the Badlands.
