I finished reading your post and was about to say Mako from Legend of Korra, but his hair isn't shaved at the sides. That doesn't mean you can't still dress as him, all you have to spike your hair.
Nightwing from DC Comics is another one that comes to mind, specifically the one from Batman: Animal Instincts to match your own hair (he doesn't have his hair shaved at the sides either but you can style your own hair and it'll still look pretty cool.)
Marshall Lee from Adventure Time is another one, too.
You can even do, if you don't mind doing it is gender bent versions of female characters with black hair (you can get away with brown), like Homura Akemi from Madoka Magica, or Ryuko Matoi from Kill La Kill. There's no one way of doing gender bents, just as along as you have the major elements of the character it'll be fine.
Hope this helps
A few other ones that I thought of is Superman, any version of him will do, as well as Star Lord/Peter Quill from Marvel Comics (or live-action, up to you.)
Male Wonder Woman would be pretty awesome too
