Quest of the Delta Knights (1993)

This action-comedy takes place on a world where the 15th Century finds Europe still caught in the grip of the Dark Ages. A young boy named Tee is sold into slavery, and bought by the beggar Raydoor, who takes him on as an apprentice. When Raydoor realizes that Tee is the subject of a prophecy, he reveals himself as one of the Delta Knights, a secret order dedicated to helping humanity. Trained by Raydoor, Tee also becomes a Delta Knight and joins forces with a ne'er-do-well painter named Leonardo (from the small town of Vinci), and a tavern girl, Thena. Pursued by Lord Vultare, minion of the wicked Mannerjay, they set out on a quest to find the lost treasures of Archimedes.
