Zombieman/Relationships

Dr. Genus
Dr. Genus experimented on Zombieman as part of the immortal series. He escaped their clutches and ever since hunted for any clues on the House of Evolution's whereabouts. After confronting him, Zombieman realized Dr. Genus' had truly given up on finding the perfect creature and decided to let them go.

Sweet Mask
Zombieman dislikes Sweet Mask and was not willing to be put under his control. He would give up his credit for the Monster Association raid if it would convince Sweet Mask to lead the surface strike force.

Saitama
Zombieman bore witness to Saitama while he was still an experimental test subject for Dr. Genus at the House of Evolution. Even still, he did not know the nameless hero by definition, only that he had a hand in his freedom. When witnessing the lower class heroes confrontation with Garou; he remembered his creators words about the mysterious limiter imposed on personal potential.
