I've always hated this character. I especially hated the fact that he was never the actual Bowser but rather some kind of mix between the Koopa King from the first SMB and Wart from SMB2. I mean, I can understand at the time the first serie came out, the producers only had the first two SMB games to work with but later they made new seasons based on SMB3 and SMW which both had clearly detailled Bowser sprites, they could have changed the villain (at least, a bit). Also, what's their deal with the koopalings design in the serie ?! They had perfect design in the SMB3 artworks and there it looks like they've been barfed and rolled over on a highway !.. but well.. enough arguing.
Here's a recolor for Bowser based on King Koopa from the Super Mario Bros Super Show. Enjoy, paisanos !
I don't like how there are yellow "streaks" below the horns where there should be green. Other than that, good job. I really like how you based your pictures on scenes from the show (Especially the one where he's diving with the tanooki power up XD)
