Marvel Super-Heroes #51

With Banner trapped and about to be evolved by the High Evolutionary, the New Men attack and stop the experiment. Banner becomes the Hulk and fights the New Men and the Evolutionary decides that the only way to stop his former creations is to do to himself what he planned on doing to Banner--evolving himself a thousand years into humanity's future. He does so and becomes a transcendent being who devolves his New Men back into animals before melting into cosmic consciousness. The Hulk is left alone on Wundagore II, the only sentient being on a lonely planet.
