So heres a ref for Rock. I think finally, after 7 years, this is his final design.

Crap drawing because I just wanted to get this done.

A little bio. And a crappy backstory 8D

Name: Rock
Age: 25
Species: Saltwater Crocodile

A bizarre mixup prior to his birth landed him in the nest in a wealthy dragon clan. It wasn't long before him and others arrived in this world. He grew up in a family with one child, an orange dragon by the name of Kyo. Both brothers departed the clan at age 18. Despite leaving together the argue, consistently. For no reason in particular Rock bares a horrible grudge against Kyo.

Rock really isn't the easiest guy to get along with. He has very few friends and trusts even fewer people. Basically hes a big douche.
