The Yeerk from Animorphs and the Goa'uld from Stargate seem overbearingly similar. They were both introduced within a year of each other. Has there been any reference from anyone assoicated with either franchise that they used the other as inspiration?
- Parasitic aliens who take completely control of a host
- They both rule the galaxy
- They were both given the opportunity to progress by a more advanced species (Asgard, Andalites)
- Both have a peaceful, symbiotic "good" offshoots (Tok'ra, Yoort)
There are many more similarities. The only differences seem to be that Yeerks need to leave the host every 3 days to recharge and that Goa'uld attach to the spine rather than the brain.
Is there any reason to think that one influenced the creation of the other?
