I wanted a shark, so I made me a shark.
Valla is an anthro sand tiger shark and space age mercenary/bounty hunter. She's got the shark teeths and a rather active appetite, so she can and will eat just about whatever, but she tries to stay active to keep that in check. Cocky and sarcastic, and pretty athletic despite the bit of chub.
Someone remind me to make a less-lazy description of her when I also make a less-lazy ref.
