If only Houndoom had 3 heads... I don't know of any specific instances of a three headed dog, so I wouldn't even know what to call it... but yeah, three headed fire breathing dog. It could be a guardian for the Underworld Pokemon God. Arceus has gotta have competition. Parallel Pokemon worlds and whatnot. Call him "Antarceus." Oh yeah.
I'm not sure what I find more annoying...the people who think that Pokemon #666 is going to be made into some sort of evil Pokemon (very unlikely)
Or the fact that when #666 gets revealed to just be this gen's version of Raticate of Pidgeotto or something we're gonna have new widespread pictures of this totally normal looking Pokemon being the herald of evil
...okay, the latter could actually end up being kinda funny.
Don't forget to check out my MegaTen themed webcomics at http://www.drunkduck.com/user/Strain42/ (Currently Updating: Persona 4TW Add-On M-F)
You see, 650 - 659 are the starter pokemon, assuming they don't do another Victini thing. 666 comes 7 pokemon after the starter pokemon. Which means it will probably be a bird, rodent, or bug.
There is no way they would have an evolution from a previous pokemon at the start of the new pokedex for the region. If anything, a Houndoom evolution would be at the end of the Pokedex, like they did with Gen 4.
