Check this out. (http://alexonsager.net/pokemon/) It's not as detailed as what NSider's Pokémon board did, but it's pretty cool how it combines two Pokémon from Bulbasaur to Golem. What makes it awesome is that you can switch the positions of the Pokémon.
Gloom x Ivysaur = win. Glooysaur.
Also, Raticate x Golduck - Ratduck.
Clefable x Meowth = derp
Nowhere near as good as good old-fashioned spriting.
LOL DO ANYTHING X GOLBAT
OR ANYTHING X GLOOM
