Both Ali Baba and Aladdin are Arabian folktales that involve caves filled with treasures like gold and coins. Both stories feature a hero or trickster character - Ali Baba features the trickster Morigana and her forty thieves, while Aladdin features the heroic title character Aladdin. Some differences are that Aladdin involves two villains, Jafar and a talking parrot, romance between Aladdin and Jasmine, while Ali Baba focuses more on courage and adventure without romance.
