I think orko should defiantly be in the flix. not putting him in the movie would be like not putting Man-At-Arms or Prince Adam in it. He was a very important character in the toon. Not to mention he was 1 of only 3 who knew who he man was.
I think he still should be a wise crack, but somehow in the film do something important to show he still can be grown up or make good decisions, so to speak.
