Thornn (Lucia Callasantos) is a fictional character created by Marvel Comics for their series, X-Force. She was one of the few Morlocks to survive the Mutant Massacre and is the sister of former X-Force member, Feral. Both had been depowered in the wake of M-Day, however, both have returned to their mutant forms (albeit without powers).

Thornn made her first appearance in X-Force (vol.1) #6 as a member of the Morlocks under the leadership of Masque.Toad, then the leader of the Brotherhood of Evil Mutants, was trying to form an alliance with the group of social outcasts, and it was Thornn's vote that swayed the opinion of the Morlocks. If they wanted to get what was theirs by right, then they needed to take it by force. Their first course of action would be to go after the defected Morlock, Feral. They are soundly defeated and Thornn is returned to the Morlocks with a warning from Cable to never mess with X-Force again.

Later when Mikhail Rasputin flooded the Morlock Tunnels, Thornn again was one of the few survivors. She attempted to save a young Marrow, but wasn't able to hold on to her with the rushing waters. Thornn was distraught and continued to search the tunnels for survivors, having no luck because Mikhail had transported a number of the Morlocks to a parallel dimension called the Hill. Running out of options, she contacted Cable and Domino to help her perform a ritual called the Ceremony of Lights—a practice where light illuminates the Alley by a series of cleverly placed mirrors and glass shards. When the Alley was illuminated the young form of Marrow appeared through dimensional walls to let Thornn know that there were Morlocks who had survived but they were too scared to come out of hiding.
