Fan Casting Hulk in Marvel animated comic show

Hulk persona was reluctant to transform back into Banner. After the Hulk was shot into space and passing through a radiation storm Rick Jones briefly found himself able to control him. They worked together to stop the Ringmaster and the Circus of Crime's latest scheme. Jones' control over the Hulk faded away. The Hulk's transformations were no longer limited to nightfall after this adventure. The Hulk became a pawn of Loki, who tricked the Hulk into battling his half-brother, Thor. This plot was foiled, leading to the Hulk, Thor, Iron Man, joining forces to form the Avengers and defeat Loki. The Hulk was a founding member of the group and together they clashed with Doctor Doom.
