So for my 1k, I have some more shitty sprites to complain about.
International RB Ponyta and Rapidash. Ug. Ly. Ponyta's is worse, it looks like a... well, I'm not really sure.
Kabuto, same games. Just the top, it would seem.
OMG BOUNCY! (And does it bother anyone else that the ball on Azurill's tail is the same size as its body?
Gen 3 Latias is kinda at a weird angle.
Yellow Clefable. Looks kinda like a creepy friend barging in on your conversation.
Keeping it in the family, Gen 3 Cleffa is oddly tiny.
Wailord's Gen 3 and 4 backsprites, respectively. Yes, that's Wailord.
Nidoking from Silver. It seems to say, "OH MY GOD WHAT HAPPENED HERE?"
Nidoqueen from Yellow raises the roof.
Gen 4 Regice looks like it's trying to fly. Trust me, Regice, you don't want to be a Flying type.
Scyther's Gen 1 backsprite. Dear God.
Caught a Girafarig in Ruby's Safari Zone. Wanted to test it out. Saw this. Back into the box it went.
Croconaw's sprite coloring had issues in Gen 2. This one, which is from Silver, gets bonus points for how goofy it looks. Crystal fixed the blue part, but
it wasn't until RS that the entire coloration matched the official artwork.
Sandshrew from DPP has this funny jumpy animation.
And last but not least, GF makes Magikarp look like the shitty fish it is. Painfully so.
Edit: Yes, I know models aren't sprites. But they serve the same purpose.
