Is it possible that Serperior is a legless lizard as opposed to a snake, since its previous stages have limbs?
Interesting! There’s a few key anatomical differences between snakes and legless lizards that we can use to check. Here’s the Snivy line for reference:
1) Legless lizards have eyelids, snakes do not.
(For all images, legless lizard is on the left, snake is on the right)
This one is kind of hard to tell. It’s a little unclear on Serperior, but Snivy certainly has an eyelid, so I’m going to give this point to Legless Lizard.
2) Legless lizards have external ear openings
Unless the things on its head are its ears, I don’t see any ear openings on Serperior. I don’t think those are its ears, since Snivy does not have them (and Snivy does not have ear holes either). Point for snake!
3) Snakes have larger scales on their bellies, legless lizards do not.
Again, this is ambiguous on Serperior, but on Snivy and Servine, they clearly have longer segments along their belly. Point to snake!
4) Legless lizard’s tongue is thicker and less forked.
This one definitely goes to Legless lizard. Serperior’s tongue is basically round.
So…these tests are inconclusive? Tied 2 to 2. Serperior could be a legless lizard. Or I wonder if it could be the opposite…a legged snake? Who knows!
