The simple sculpt is reflections toys like Microman or those early days Power Ranger toys. You know, the ones with big cylindrical hinges ignoring any attempt to hide it in the sculpt. The backside is nothing but screws. The molds for toys were just not capable (or economical) to produce high detailing. Buzz is also following the same type of toys, bit nicer since he is a bigger figure, so you could say these three are much more similar to him.
They should be rounder honestly, but I think then they looked less toy-like so we ended up with low-poly looking fellows instead.
