I didn't realize that there weren't that many hybrids...
Also, that's a LOT of Pokemon that have 205 or 250 as their number.
F8, FA, and FF use the real sprite of the Pokemon, and FD uses the ghost of Marowak... for some reason.
00 has a number of 000 like Missingno. does, but apparently doesn't have a sprite.
