I don't know if I'd put Bludgeon in the same league as Ironfist and Razorbeast, as he was already a prominent character in G1 while the toy was still current. Furman loved taking lesser known current toys and using them in his stories (e.g. Wreckers)... part of the reason was to avoid conflicting w/ Budiansky's stories. Razorbeast and Ironfist on the other hand are toys that become popular years/decades after the toys came out and sorta retrospectively became more popular.

Anyway, others may include Rotorstorm and Pyro. Sunstorm also became popular some time after the eHobby toy came out. Arguably Acid Storm too -- the original Deluxe figure was a massive peg warmer, but the MP seemed to have sold out quickly.
