I'm sorry but I'd say you're jumping the gun without a proper understanding of these 2 figures. They're similar only in that they are from the same team & series of releases. And as with any SHF sub-line whether it be Drive or Gaim or anything else, they do share some parts like the leg assemblies. But Bikel is not retooled at all from Fire. That's like equating Drive Type Wild to a retool of Drive Type Technic. Do they share SOME parts? Sure. lots of figuarts do.

Things like shared parts decrease production cost. But because Bikel is a mostly new figure altogether, and a limited run web exclusive, the tooling for those parts is higher. Hence the slighlty higher price you're trying to equate it to in Lord Baron. It's a negligible difference of like $4 USD. But those are entirely new arms, a completely new torso, new headsculpt, waist piece. Everything is new aside from the obvious legs & reused pistol.

I'd hardly call this a yellow Fire.
