Additionally, The Mergefright will receive a third additional tail or rather the remain, an endoskeleton tail (Which he has already attached the two coated tails from Mecha Taingle).
More outlier wires were added in the default appearance...
(Changes: Red Rings instead of Golden Rings on his arms / limbs and so on + changed ears) and other slight changes / will be moved to the swapped version.

So, I leave this drawing and info and gotta go.
