I really like that picture.
I'm afraid though, you are quite mistaken. He-Man is not cool, or awesome. He is a badly animated, moralising, American 'jock' appearing in an ill thought out advert for poor quality toys, masquerading as entertainment.
His powers seem to include - not doing very much, being a little bit strong, being able to throw baddies into shallow pools of water where they then sit, completely unharmed saying "Bah!".
In conclusion - He-Man is crap.
Except in this excellent picture.
