Link 86 said:the symbiot is a mutual relationship where both sides gain the benifits the Goa'uld are jus a parasite, so the host would not be harmed nor would it gain anything, Tok'ra never heard of them but yea, basically its not what he is lookin for
Herobizkit said:You might give the Psionics/Expanded Psionics Hanbook a once-over. One magic item contained within is called a Psychokinetic skin, which is essentially what Venom is. The skin covers the entire body and grants the wearer certain boosts and abilities, and there are several different types. IDHTBIFOM, so I can't quote them to you here.
Kristivas said:Tok'ra are the good (or neutral) version of the Goa'uld. They actually share a body with their hosts. They switch back and forth between who's concious and whatnot. Becoming a host to the Tok'ra is voluntary, they aren't taken over or used the way Goa'uld use their hosts.
