Normally we think of Bowser as a barely credible threat, a comic figure who is constantly stymied by Mario and Co. at every turn. While Mario and Peach can always be cute and soft, Bowser's art design typically straddles the line between silly and barely menacing. The Paper Mario series did little to bolster Bowser's standing, painting him in comic 2D and illustrating him as bumbling at best.
However, Bowser's portrayal in Super Smash Brothers Brawl allows Bowser to get a little pride back. In normal guise, he's a hulking, threatening beast, but when he gets a Smash Ball, well... See for yourself.
ROAR!
It feels good to smash Peach and Mario as a great, powerful, hulking beast once again.
