“Round Robin: The Sidekick’s Revenge! Part Three: Total Eclipse of the Moon…Knight!”
Writer: Al Milgrom
Artist: Mark Bagley
Spidey, Moon Knight, Night Thrasher, and Punisher catch up to Midnight at one of the branches of the Secret Empire. Not in time to rescue Nova. But a fight ensues with a large number of Secret Empire goons and the Seekers (Chain, Sonic, and Grasp). Spidey and the gang fail and the bad guys get away. Midnight brings Nova to the main HQ and they begin adding some enhancements to him. Secret Empire needs a new leader and Midnight secretly wants to take over. The operation on Midnight is painful and a nurse friend of his leaves. She tells a technician outside to plant something in his spinal column. He refuses at first but she does something (unknown to us) with her face and he fearfully agrees.
