I perfer Houndoom. Because it is a dark type and is a dog like me in the Zodiac. :P
I like Houndoom the most because it is a Dark/Fire type, and it has extreme Spec.Atk!!!!
This seems like a rather pointless thread; there is no apparent relation between Houndoom, Clefairy and Ash which you're determining between. Right now, you should probably go to the favorite Pokémon thread unless you have a good reason to want to know which of those three in particular is liked the most.
Yeah... this should probably be closed. o.o;
