Bowser

Bowser is the main antagonist of the Mario franchise and is a major character in some of IronYoshi1212's videos.

Characteristics
Bowser is the king of all the Koopas with a pretty basic goal; to capture Princess Peach, rule the Mushroom Kingdom and get rid of Mario! In the IronYoshi1212 universe, that hasn't changed a bit, but Mario teamed up with Bowser in the SM64 Super Bloopers movie in order to stop the Bob-omb King.

SM64 Super Bloopers
Bowser made his debut in the series in Battle With Bowser, where Mario must traverse the Dark World in order to face him. After much trial and error, he finally makes it and begins his fight against Bowser, who taunts him. Ultimately, Mario calls him a "Mutated Squirtle", and places him near a bomb, defeating him.

Bowser would later return in the Valentines Day Special, where Mario goes to wish him a Happy Valentines Day. Bowser didn't want any of this, and promply burns Mario on the butt and tells him that bad guys do not celebrate Valentines Day, with the exception being the Goombas. He also tried to rape Mario, but Mario fell off the arena before he got the chance.
