Re'tu rebel faction
An alliance of hundreds, if not thousands, of Re'tu who oppose the governing body on Retalia and its tactics of war against the Goa'uld. The rebels believe that all potential Goa'uld hosts must be destroyed, in order to force the enemy eventually to die out due to attrition.
Re'tu rebels are armed with transphase weaponry and the same phase-shifting abilities as normal Re'tu, making their squads of warriors invisible and thus easy able to infiltrate and destroy their targets.
Show and Tell - The S.G.C. and a team of Tok'ra operatives investigate the Re'tu rebel faction on a desolate world and find the reports to be true.
