He became Bruce's friend in his first appearance, in Amazing Fantasy volume 2 15, in a story called Mastermind Excello (that was supposed to be Amadeus's codename, it's the name of a Golden Age character). That was published in 2004, so would be 3 years ago in-universe at the most.
If you saw a teenager in Hulk stories set earlier than that, it was probably Rick Jones.
