Superman #356

In "Battle of the Super-Hyper Powers!", Superman faces a surprising visitor when Vartox arrives on Earth, claiming to have found a new home on the planet Tynolan—where his Hyper powers are essential. While pretending to train with the Man of Steel, Vartox subtly warns Superman that the Tynolan people are using manufactured disasters to keep him bound to their world. As the two engage in a staged battle to avoid suspicion, the true nature of Vartox’s mission begins to unfold.
