The new Venom series is out with the veteran Flash Thompson using the symbiote Venom as a tool in the military. I haven't picked up my copy yet, but my provider's holding a copy for me. This series should be pretty interesting, especially with the new "Fear Itself" run.
The Symbiote itself fears the lack of a host (needing someone's emotions to feed off of to survive). It feeds into the spots of Flash's attitude that were addicted to alcohol, making him become addicted to the Venom (as the last host, Mac Gargan, was) and the strength that the alien can give him.
