Show me your OC with spiky teeth!

I personally find there are usually about 4 kinds of spiky teeth. The piranha (Qiang/slide 5), the shark (Rekken/slide 6), the big ones (Radget/slide 7), and the vampires (Yoyo/slide 8), but I'm interested to see if you think there are more!, I'm sure I must be forgetting some, lol
