Sorry, which mythological creature is Silverbolt based on? I thought he was a fusion between an eagle and a wolf. I know that winged wolves are popular in fantasy art, but even then most of them appear to be images of a wolf with large bird wings sprouting from its back. Silverbolt isn't just a wolf with wings, his front legs are eagle legs and he also has an eagle's tail, not a wolf tail. Quickstrike was also a fairly well executed Fuzor toy, yet I know not of any mythological creatures which has the body of a scorpion and a cobra for a tail. It seems that Hasbro chose the two best Fuzor toys for the show; the others aren't as well designed IMO; that's not to say that they're all bad... I'm rather fond of Air Hammer.

The only Beast Wars/Machines Transformers I can think of who have beast modes specifically based on mythological creatures are:
+ Transmetal 2 Megatron (dragon)
+ Heinlad (tanuki)
+ Galvatron (dragon)
+ Battle Unicorn (unicorn)
+ Beast Changer (werewolf, dragon)
