Put simply, Hasbro ruined a fairly decent toy by making this monstrocity.
This should have been the mould release they do later of a mould, giving it a new head and colour, and making it a new character... as it doesn't feel like Ratchet, even a tiniest bit. Giving it a completely new head and completely resculpted, this toy should have been called Dinobot, and Ratchet should have been released with a Ratchet head and Ratchet colours.
