Pokémon X and Pokémon Y

What exactly is the trend per say?


Charmander > Charizard. Two legs to two legs.

Cyndaquil > Typhlosion. Four legs to two legs.

Torchic > Blaziken. Two legs to two legs.

Chimchar > Infernape. Two legs to two legs.

Tepig > Emboar. Four legs to two legs.

they seem to like making the fire starter 2 legs, but i felt like this time they'd break out of it and make it 4 legs. i didn't add the last part though ._.
thinking about that, i find it funny that snivy went 2-legs ->no legs

@above: i haven't seen that before actually, and look at that majestic motherfucker. he's arcanine levels of badass.
