Tuma is the former leader of the Skrall in the Shattered Mirror Universe. Following his defeat, he became a mercenary, leading a team made up of Stronius, Metus, Fero, Branar and several other Skrall. They were hired by Blackout to kill Ynot. His ship was attacked by Crona, causing him to fall out and into the cathedral where his targets were. Then Zev Raregroove used some sort of mirror to remind him of how he masterminded the extermination of the Skrall, and then started beating him up while moving too fast to even be seen. D-Klak tried to help Zev, but Nadle stopped him.
