Seibertron have posted up another one of their top-5 postings, and this one is actually interesting enough to mention here.
It features some of the confusing or redundant parts that are on Hasbro Transformers toys, and even though I already knew why almost all of these exist (except Optimus Minor, whom no one probably knows why it has extra arms), I thought that there might be some people here who might be enlightened by some of these.

It includes...
- BW Transmetal Optimus Minor having split arms in robot mode (no one knows why... probably so that it wasn't criticised for having no "transformation" element to all of its limbs).
- Gen1 Dinobots having seats (left over from the pre-Transformers Diaclone versions, which had pilots).
- Universe Galvatron having legs (a well documented story about how this toy was originally designed to have three modes and a Voyager size... but then scaled down to Deluxe size, and having the third mode abandoned without removing all of the parts that only apply to the third mode).
- BW Transmetal Ultra toys having cockpits (another story revealed at the time, about the toys intending to have pilots, but the concept was dropped by Hasbro, but later included when TakaraTomy released the blue Cryotek in Japan).
- Gen1 Perceptor having an extra wheel on its back (similar to the Dinobot seats, as it was for a pre-Transformers tank mode that Hasbro didn't officially document with their release of Perceptor).
