Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Collage of my brainstorming so far. I think the pirate petrel, greaser griffin, and sniper condor (in that order) are my strongest candidates, but we'll just have to wait and see.
I made a quetzalcoatlus! I didn’t like the idea of doing a bird, but a pterosaur seemed more up my alley. To play up the Dark type, I wanted to go for something intimidating, so why not go for the biggest creature to ever take flight? Quetzalcoatlus have some really freaky anatomy, but they have some cool features too like their gigantic beaks and fun crests - in this case meant to loosely resemble an old cartoony blast effect along with the tail “feathers”.
This is still quite WIP, not sure if I’ll stick with it but if I so I may mess with the proportions and patterns a bit, and I’ll probably want to include some supporting material to show off its torso and hind legs better, as well as doing various actions. Stay tuned!
