Rajah

Rajah is Princess Jasmine's pet tiger. He clearly loves her very much and is very protective of her, When the snooty Prince Ackmed introduced himself to Jasmine Rajah attacked him and tore a hole in his pants, he is later seen chewing on a piece of his underwear. At first Rajah wasn't too fond of Aladdin, and often growled at him, but by the end of the movie he has grown more comfortable around him. During the events of the movie he gets turned back into a cub by Jafar when Jasmine sics him on him, although he later gets restored when Jafar is defeated. In The Return of Jafar he is seen chasing Iago as he knows he worked for Jafar and tries to eat him.

Although primarily a mere peripheral character in the TV series, Rajah played a prominent role when he, Abu and Iago were the only three unaffected by Sadira's use of an unspecificed magical sand that somehow altered history so that Sadira was the princess and Jasmine the street rat; with the three animals the only ones who knew that history wasn't the way it should be the three escaping the palace to find Jasmine and restore the world to normal.

He serves as Jasmine's usher in Aladdin and the King of Thieves.

Although tigers are traditionally found in South Asia and not the Middle East, it is not unreasonable to assume that owing to the Sultan's wealth he was perfectly capable of having one imported as a gift for Jasmine at some point.

Rajah was voiced by Frank Welker.

Trivia
A slight goof happens when Rajah transforms into a cub. He meows like a housecat, but in actuality, Tiger cub cries sound nothing like housecat calls.
