But oh, how I wish Med'an did not exist in official canon. It's one thing to have an overpowered character in a comic book introduced for some sort of overarching epic tale; it's another thing altogether to try and shoehorn that character into a franchise full of characters that have a small spark of reality to them. Don't get me wrong -- there were plenty of things I loved about the comics series that were taken into canon. The split-personality Varian was a really intriguing element that has been pushed into what ultimately I see as a really unique way of developing his character beyond random king #3 or #4.
Med'an, on the other hand, has no redeeming emotional aspect; he's just a flat-out superhero. He doesn't appear to have any weaknesses whatsoever, and his introduction threw a wrench into Garona's character that I didn't particularly care for, not to mention Medivh's. His arrival seemed like it was solely for the purpose of telling a good superhero comic story, with no real root in Warcraft. And the fact that he's the hybrid of three races all from different planets is just a little too over the top from the standpoint of simple biology.
