Loomis was a slave captured by the Zenda Brothers Circus after the Invasion of the United States.
Like the other slaves, or "Donkeys" as they are sometimes referred to, Loomis was captured by the Circus leaders Alfonso and his wife Leena by one of three methods: Losing to Leena in a midnight blackjack game, believing that Leena is dead and approaching her child before being taken out by Alfonso or believing that Alfonso and Leena's child is sick and getting captured when trying to offer aid. Loomis and the other slaves were captured and used to pull the Zenda Brother's Wagon from town to town. Once they reach a town where Ringmaster Jack could gather an audience, the circus held shows where an unfortunate slave had a fight to the death with El Diablo a captured Steelhead. The Slave usually lost.
Loomis is described as having black hair, penetrating eyes and dark skin, due to being a captive he was also unshaven like the rest of the prisoners.
As a slave, Loomis demanded that the other slaves should equally pull the circus wagon along with him but was quite happy giving Capelli and fellow slaves information about their ordeal. For some reason, the Clown guard Bam-Bam took a strong disliking to Loomis, making the other slaves believe that he would soon be picked to fight El Diablo.
