Synopsis:
After repairing the Metal Men from the damage they suffered at the hands of Chemo, Doc Magnus returns to the spot where Chemo was destroyed. A freak bolt of lightning causes Chemo to be ressurrected, and the chemical menace sprays Doc with chemicals. Doc escapes, but not before his body grows to tremendous size, turns to metal, and becomes radioactive.

Doc himself has become a menace and vows to exile himself into space. Tina follows him, exposing herself to radiation herself. The rest of the Metal Men elect Tin as their new leader and battle Chemo.

The Metal Men divert Chemo to Doc’s rocket and the chemical man is launched into space with Doc and Tina. Upon reentry, Chemo is destroyed, but his chemical body combines with the rocket and restores Doc and Tina to normal. Doc returns to the lab with Tina and once again repairs his damaged robots.
