Historically, I have kinda flip-flopped between drawing Forbic as a very large, overweight alligator and a smaller, somewhat anthro-ish dragon. Here we see him as the latter in a fun, sorta squared and exaggerated shape, but I had a lot fun making this one! A little rounder in the middle than I typically draw the smaller, dragon-Forbic 'cause he's usually kinda small for more prey-type shenanigans. However, some people (myself included) do like seeing him still greedy, hungry, and large.
Traditionally, Forbic originally was just the dragon self, but I grew more a fan of a larger, more predator-friendly size and with it took to a new shape/species overall. There's not really much rhyme or reason to it, just whatever mood strikes me or whatever my friends would prefer I s'pose.
