How many Transformers can you find that coincidentally look really similar to something else?

For example, I've always thought that Mighty Orbots bore a very strong resemblance to G1 Blaster:


Can anyone else find any others? Remember that it must be (as far as you know) coincidental and not intentional like say Animated Bulkhead's resemblance to Crunch from Mighty Orbots, or G1 Jetfire's resemblance to Macross' VF-1S etc.
