The Incredible Hulk: The First. Engaging 2parter in which David finds that someone else became a version of the Hulk 30 years earlier. Actually finding the person and trying to replicate the cure, David fails to realise that not only does his new "friend" actually miss being the Hulk, but is also a homicidal a-hole... and is unable to prevent him from recreating the experiment and becoming the Hulk again... Hulk vs another (evil) Hulk is such an obvious idea it's only surprising it took them four seasons to do it!
