12th place seems a little low for a dragon Pokemon as old as the universe itself and who is responsible for the creation of space, but who am I to judge? I suppose it does look like a kaiju that fused with some pinball bumpers and, uh, something phallic to form its neck/head, which isn't quite as cool-looking as some of the other uber-powerful gods that came into play in Generation 4. Still, it's a ridiculously great Pokemon and - again - literally a god. Gotta be tough out there for Pokemon atheists with this many gods running around.
One of the best things about Gallade is that it provided an evolution from Kirlia that (for the most part) didn't lead to unbelievable amounts of creepy fanart (like a certain other evolution). On top of that, it's hard to not love a Pokemon with swords for arms and standing in a constant fighting pose and OH SHIT nevermind there's plenty of creepy fanart for Gallade too.
A badass giant turtle with a tree growing on its back? So much better than badass giant turtles with no plantlife living on their backs (lookin' at you, Tirtouga). The fact that Torterra looks this cool and still placed the lowest of all the Gen 4 starters speaks highly to just how badass all these starters turned out - especially since its the only one who has a big tree growing on its back.
Until Pyroar reared its majestic mane, Luxray was the closest thing we had to a lion Pokemon - and even still, it's the best electric-type lion Pokemon (unless you're counting Raikou, but that's sorta debatable, right?). According to its Pokedex entries, it's made pretty clear that Luxray lives up to its name-pun and can see through most things (lu-x-ray), which should come in handy when its looking through the Pokeball its trapped inside and seeing all the battles I won't let it participate in.
