Nothing is known of Kel's life before he was seen fighting against Belus on Earth alongside Omoroca as a freedom fighter. Though their efforts ultimately failed, with Omoroca being killed and Kel himself becoming the personal trophy of Belus, their fight inspired the Tau'ri to fight against their Goa'uld oppressors and drive them from the face of the Earth.
Upon leaving Earth, Belus took the captured Kel with him back to Goa'uld space. Within weeks of this happening, Kel once again attempted to kill Belus in order to gain his own freedom and to avenge his fellow Ohnes. Though more successful this time, managing to severely damage Belus' host, his attempt was once again unsuccessful as Belus chose to take Kel as his new host. This act caused the former freedom fighter to forever be a prisoner of his most hated enemy. (RPG: "Fantastic Frontiers: Stargate Season One")
