Bowsar

Bowsar is Bowser's identical twin brother who was blown up by Mario for no reason.

Biography
Bowser introduced Bowsar to Mario after the plumber entered the sole platform in Bowser's Lair. Both twins tried incinerating Mario but the latter grabbed Bowsar by his tail and hurled him to one of the spiked detonators at the tips of the platform, killing him. Bowsar's cadaver was blown to the other side of the platform. Bowser tried to retaliate on Mario but was also swung to a A-bomb, though Bowser survived the blast.
