All of the Fan Club action figures are commissioned by the Club and made by Hasbro using mostly existing Hasbro sculpts/molds. The Club has commissioned new heads and even paid to have some existing tools rehabbed. Hasbro basically makes older molds, that aren't being used, available to the Club to create new characters or new versions of characters.
There was actually just a debate on Hiss Tank about whether or not to include the Fan Club figures in a "complete" collection, meaning are they Hasbro toys that are canon or are they some type of bootleg/unofficial creation that should be thought of outside of the retail store Hasbro collection.
IMO, they're canon because they're made with full approval of Hasbro, by Hasbro. I don't see it any different than a store exclusive requested by Walmart. In most cases, they're better because the Fan Club has had those new heads created for some of their figures.
The Adventure Team figures are really cool. I've picked up the Venom/Commander and Land Adventurer sets so far but have to get on the other two soon. The bodies use existing parts from various 25th figures and the heads are new.
