Ooh, I want ludicrous type mixes, like Grass/Fire and Dark/Fighting. I have too many Pokemon ideas...
-Garghoul, rock/ghost gargoyle
-Dreadusa, steel/dark medusa-like Mawile evolution
-Strangela, grass/ghost Tangela evolution
-Hitmonarch, fighting/dragon hitmon ancestor, like Mewtwo is to Mew, but stats are more fair
-Compasal, rock/electric Nosepass evolution
-Jestive/Jestivity/Jestival... Jestive is a psychic baby clown with a large bouncy ball, Jestivity is psychic a smily slim jester with a ball, Jestival is a psychic/ghost jester huge and round
-Peggle/Peckadoo/Poultagust... Peggle is a normal egg-shaped chick, Peckadoo is a normal/flying chicken who is more tame looking than Combusken, Poultagust is the flying/ghost type who results from cooking Peckadoo. I'm undecided if Peckadoo should differ in looks and attack depending on sex; eg, the female has eggy moves while the male is more likely to fight.
-Bluumier, fire/grass flower-tail cat
-Burrowatt, ground/electric porcupine with a spiked ball tail
I have a TON more, but I don't feel like listing them.
