Dragonlord.

Dragonlord is a treasure-obsessed hunter whose best friend is a Tyrannosaurus Rex called Blaze Falcon. Rather than hunt for yet more treasure, however, Blaze just wants to hang out and play video games. But when he's kidnapped by the evil Dreadmancer, Dragonlord must pull together an Avengers-like team of bonkers heroes to save his dino buddy.
