A question for anime/manga fans...
 

This may be a long shot, but figure that there may be a few of you in here!

I'm trying to remember the name of a movie/show (i'm not entirely sure, but I think it was a movie). I seen it years ago, and the only thing I remember is that the main character had a marking on the palm of his hand (i'm pretty sure it was a circle.) There were others with the same marking, which set them apart from everyone else (were they some sort of space knights? Princes? I can't recall!) He may or may not've been searching for his father (mayhap that's Jayce & the Wheeled Warriors i'm thinking of there!) There was a humanoid pterodactyl guy who's wings could transform into arms, and he too had a marking on his palm. I'm sure the main guy came across and teamed up with this winged dino terror. Other than that, I can't recall. I remember loving it though and would love to check it out again. (Also, was there a nightclub scene? Or is that from some other show? Geez...)
