Character name: Bowser
Character Gender and Species: Male, Koopa?
Originating Game: Super Mario Brothers (probably)
5 words to describe personality: Megalomaniacal, Angry, Blusterous, Malicious, Ignorant.
Battle Skills and Weaponry: Bowser fights savagely not unlike an animal. He has prodigious strength and uses his claws, the spikes on his shell, his fire breath, and in some cases even just his shear mass to wreak havoc upon that stupid plumber, his goofy looking brother, and even some of his own minions.
Pokemon or other partner (examples include: Navi for Link, pikmin for Olimar, Toad for Peach): His Koopa army, but I figure in this he would mostly just have them fetching and carrying for his hairbrained schemes.
Brief History: The king of the Koopas has been an enemy of everyone's favorite Italian plumber, as well as the Mushroom Kingdom, for years. Ever since the first time he laid eyes on Princess Peach, he's wanted to make her his own, and for him the best way to try and do that was a show of power by kidnapping her and sending his armies to conquer her kingdom. And ever since the first time he nabbed her, Mario has been a thorn in his side.
In more recent times, after the recent Smash Bros. tournaments and the incident with the Subspace Emissary, wherein he fought against the Smash Brothers, and then when he realized the evil plot he was a part of, worked with them to stop it, he is coming to the newest tournament with a slight bit of trepidation, not that he really knows what that word means. For once, it might not just be business as usual when he shows up and he knows some might hold a grudge against him. But he'll probably just handle it the usual way, by being big, loud, and mean.
I hope that works for everyone. Let me know if anything needs changing.
