Jafar (voiced by Jonathan Freeman) is one of Jaden's sworn enemies, and is the main antagonist of Jaden meets Aladdin. He is the royal vizier to the Sultan of Agrabah that wanted the magic lamp in the Cave of Wonders to become sultan. Jafar had Aladdin and Jaden go in after it (since they were the only ones who could enter the cave), but the cave collapsed on itself, and Jafar lost the lamp. It was than that his sidekick Iago came up with the idea that Jafar marries the Sultan's daughter Princess Jasmine in order to become the Sultan. Aladdin showed up as Prince Ali, and Jafar saw him as a threat to his plan. He attempted to drown Aladdin, but Genie saved Aladdin. It was than that Jafar recognized Prince Ali to be Aladdin, and had Iago steal the lamp from him. With Genie under his control, Jafar wished to become the Sultan of Agrabah, but no one would bow to him. Jafar used his second wish to become the most powerful sorcerer, and had Aladdin and Jaden banished to a frozen wasteland. Aladdin and Jaden managed to get back to Agrabah and faced Jafar. Jafar turned into a giant cobra and tried to squeeze the life out of Aladdin, but Aladdin tricked Jafar into wishing to becoming a genie, and ended up imprisoned within his own lamp with Iago.
