no.... the hulk is just a state of Bruce banner that is huge strong and nearly uncontrollable that pretty much rampages for revenge yet Bruce is slowly gaining more control in the newer issues.. so if he had a sidekick than the sidekick would go bye bye pretty fast! Originally, when he first gained his powers, the Hulk was often accompanied by Rick Jones (who was mainly responsible for him gaining his powers in the first place). Rick stayed with the Hulk, on and off, for years. At other times though the Hulk has had other companions such as Jim Wilson, Kate Waynesboro, the Recordasphere, and Amadeus Cho. Aditionally he has been the member of many teams such as the Avengers, Defenders, Pantheon, the Order, Titans Three, Heroes For Hire, the Warbound and a temporary alternate Fantastic Four.
