Jasmine's tiger Rajah has been confirmed for Guy Ritchie's live-action remake of the Disney classic Aladdin. He is first seen snarling and seemingly ready to attack Aladdin as he arrived on Jasmine's balcony, but the tiger immediately pounces on the boy and gives him a welcoming lick. He is Jasmine's protective pet bengal tiger and best friend. The Cave of Wonders is a location in the animated film, Aladdin.
It is a hidden cavern filled with vast riches and magical artifacts, most notably, the genie's magic lamp. Rajah is a supporting character in the sequel. The cave can only be entered by an individual whose "worth lies far within"—the diamond in the rough. Perfect for putting fear in lame suitors (the aforementioned Prince Anders), but showing a soft side with a big tiger lick for Aladdin. Jasmine's Tiger Will Return in Disney's Aladdin Remake. Rajah in The Return of Jafar.
Tiger from An American Tale deserves a mention. Rajah is a minor protagonist of Disney's remake of the 2019 film, Aladdin. Tigers are the best judge of character.

Raja, Jasmine's tiger in Aladdin is the most popular cartoon tiger, following maybe the Pink Panther (who technically isn't a tiger).
