I went to 4chan(first time ever..weird ass site but anyways) In the pokemon section someone posted this and said this is the sprite that was shown to 1 of the web masters as proof. (im not saying i believe it or W/E and im not endorsing this...just simply showing what I find.)See, this. This is what is weird. How... why in the world do they just have SPRITES? Not official art, not screenshots, not images, SPRITES? By themselves? That's just very very strange. Man I wish we could just get to the bottom of this.
Also, I don't see why people are even making a big deal about quadrupedal/bipedal/whatever anyway. No starter has never lost all of their limbs, so what? No starter has even been a snake either. No starter has ever become quadrupedal? So what? There's a first time for everything, it makes Mijumaru's line more distinct from other starters if it's true.

supposedly from the pokedex screen

I'm no graphic designer, that's my fiancé. So...you tell me. This image that's been anonymously sent to me, with a note attached saying it's the one Melkor has...is this legit? It's apparently supposed to be from a Pokédex screen.
