Abu acts as pet, sidekick, and best friend to Aladdin. Rather than being a genuine 'character', he is used as somebody for Aladdin to voice current thoughts, or sometimes to help him out of trouble - or sometimes to get him INTO trouble.
He makes his initial entrance while helping Aladdin escape from the Palace Guards after stealing bread. Unfortunately he is attracted to a stall selling jewelery and has to be dragged away. Later in the bazaar, he helps Aladdin to steal a melon for breakfast, and when Aladdin meets Jasmine, he is almost caught picking a pocket. He also steals some apples. He doesn't really appreciate Aladdin's attraction to Jasmine, thinking it will spoil their friendship.
When Aladdin is imprisoned in the palace dungeons, Abu, who had not been captured, arrives and picks the locks of Aladdin's chains.
In the Cave of Wonders, Abu wakes up the Carpet. He is attracted to the many fantastic jewels and finally grabs a huge ruby out of a monkey idol's paws, initiating the destruction of the cave. When Jafar is about to stab Aladdin, he bites him on the arm, but is thrown into the cave with Aladdin.
When Aladdin awakens the Genie, Abu is seen to be a tool for a mode of transportation, and goes through many changes before Genie decides on turning him into an Indian elephant (with a remarkably long monkey's tail).
After Aladdin returns to Agrabah to stop Jafar, Abu helps out by pinning and knocking out Iago, keeping him from alerting Jafar to Aladdin's return.
Abu and the rest of the main cast from Aladdin make appearances in this sequel. He joins Aladdin at palace for his new life with Jasmine and the Sultan. He maintains his selfish attitude while helping the gang defeat the revenge-seeking Jafar.
Abu makes regular appearances in this television series, often paired with Iago. Although he is still a casual thief, he has shown definite signs of a conscience, being particularly heartbroken on one occasion when he thought Aladdin wanted him to leave forever, Aladdin subsequently traveling directly into the headquarters of the Forty Thieves to rescue Abu.
Abu appears once again as a sidekick, although in this installment he hangs out with Genie and Iago more than Aladdin. Iago and Abu are now "partners in crime," as Iago calls it.
Abu appeared in "Hercules and the Arabian Night" alongside Aladdin, Jasmine, Carpet, and Genie. Abu is captured along with Icarus in order to lure Aladdin and Hercules into fighting each other, but they manage to escape.
