...I'm not sure right away. It's been so long since I really watched cartoons. When I start thinking about it though there are all sorts of characters that I used to love from Mask, Voltron Z, Thundercats, Transformers, and Underdog. For some reason though I used to have this one weird semi-obsession with one character from GI Joe. The white ninja (which until looking it up a second ago I had completely forgotten was named Storm Shadow) was so amazing. I used to have his action figure and for some reason I would have him fighting against these huge groups of people and he would always school them. No questions. He could be going against the guy from the Hulk with the rotating head, Cobra Commander, the whole crew of M.A.S.K and Panthro and Cheetara for good measure and it would be a proverbial blood bath of ninja stealth-ness and sly moves.
Now for some reason I still feel like he's the coolest cartoon character. I mean, look at the other stuff that was coming out near that time. The Gummi Bears? Who in the world thought that was a good idea. Scooby Doo? Worst cartoon ever; don't even get me started on the movies.
So to summarize, Storm Shadow is better than all other cartoon characters combined, no doubt about it. I don't even care that he was a bad guy in the show, he was the hero of my action figure filled childhood.
