He takes pride in his hair, and his shampoo collection.
Whenever one of Hannah's song becomes a hit, instead of attributing it to the singer, he, jokingly, takes the credit himself.
He now goes to college, which he often brags about.
Jackson and Miley constantly bicker and compete for their father's approval.
Even his own mother admitted that he sings like "a regular tone deaf walrus." During Miley's nightmare in "I Am Hannah, Hear Me Croak" he becomes a rock-star sensation named Bucky Kentucky. In "Debt It Be" he plays an old woman at a rest home, in "You Give Lunch a Bad Name" he plays a pot-bellied health inspector, and in "Knock Knock Knockin' on Jackson's Head" he gives a believable performance of having suffered amnesia.
He is also good at impersonations, such as Elvis Presley, Ozzy Osbourne, the "Godfather", and Arnold Schwarzenegger.
Jackson is a very regular character in Hannah Montana.
In the episode "Judge Me Tender", he gets a traffic ticket and Robby Ray makes him pay for the ticket and he states he is not working at Rico's anymore so he has to clean up their upstairs attic.

He is a loving and caring father, but knows when serious discipline is necessary. Jackson Rod Stewart (Jason Earles) is the older teenage brother of Miley Stewart and son of Robby Stewart (he is possibly named after singer Rod Stewart).
He is known for his goofy, lazy and disgusting habits.
