The post about Nomads, goa''ulds and copyright infringements
1) goa'uld take human hosts.
2) goa'uld are evil.
3) goa'uld have four tentacle thingies.
4) goa'uld's host's eyes glow.
5) goa'uld's intent is to take over the galaxy.
And many more.
PS: Goa'ulds are from the Sci-Fi channel series 'Stargate: SG-1', and to a much lesser extent, the new spin-off 'Stargate: Atlantis'.
