#stickler

My first point! Stickler changes color in the sun, a very common trait in diurnal reptiles because they frequently bask in the sun. As seen here, Stickler can be seen becoming noticeably more vibrant when seen outside!

Secondly, his hands. His hands are unlike all the others in hell, his are longer, with long claws, noticeable joints, and a very very long index finger! This is also commonly seen in reptiles, their hands are adapted for their climate and look very similar to sticklers!

And his horns! This may be a bit of a stretch but it seems like his horns are a lot smaller than other imps, and a lot more dull. The other imps seem to have a lot more mammal like characteristics, horns included! And the horn size doesnt appear to be effected by sexual dymorphism, meaning its consistent between males and females.

Some reptiles have horns, and unlike mammals, they are a lot shorter and made out of a different material as well!
