Legion of Super-Heroes (1989) # 4

With Tasmia, Shadow Lass, never truly recovering from the death of her love, Mon-El, the council of Talok VII decide to name her cousin, Shadow Kid, the new planet protector. Suddenly, Mon-El arrives to greet Tasmia in her home, much to her shock. Mon-El explains to Tasmia that a part of the Time Trapper is in his body, which is why he is not dead. The couple realize they need to visit Brainiac 5 to help Mon-El in his precarious situation. They reach Brainiac 5, and amidst his testing, the Time Trapper plucks Mon-El from there and places him somewhere else, so he can take control. Meanwhile, a probe robot prevents Brainiac 5 and Tasmia from following suit, but Tasmia makes short work of it. Time Trapper explains to Mon-El that he created the Legion of Super-Heroes inadvertantly, and if the Time Trapper dies, time will be changed and Mon-El will not exist anymore, since he was founded in a pocket universe. Mon-El is willing to take that risk to destroy the Time Trapper and everything fades to white after he delivers the final blow.
