The First Generation of Pokemon had some pretty bad sprites. Some sprites looked better in Green than in Red, but some looked worse.
Pick a Pokemon and say whether you think it's better or worse in Green.

There are some obvious ones, like Koffing is better in Green:

So is Golbat:

Mew is the most awful looking pokemon in Green:

Thank God they fixed it in Red!
I think Golbat looks really bad in both games. Golbat is highly asymmetrical in Green (it's more pronounced in Green than RB) but I do agree on Koffing.
Gastly is awful in both games!

Kingler is better in Green! One claw is bigger than the other. But they're both the same size in Red.

Hitmonchan is worse in Green. Do I even have to explain it?

I like Gastly in Green. It looks more like the the living ball of deadly gas like it's supposed to be. Gengar and Haunter look pretty good as well.
Ivysaur is better in Green!

Why is Ivysaur on two legs?
Drowzee has three fingers in Green, but has five in Red.

Exeggcute is better in Green! What's with the giant egg in the middle?

I think Nidoqueen and Nidoking look better in R&B than in Green.
