Perhaps you're thinking of:
* "Steel Fang" - This is a move that some Steel-type Pokemon can learn.
* "Steelix" - This is a Steel/Ground-type Pokemon with a very hard, steel-like body.
To help me figure out what you meant, could you tell me a little more about what you're looking for? For example:
* What type of Pokemon are you thinking of?
* What is this Pokemon's ability?
* Where did you hear about this Pokemon?
I'm happy to help you find what you're looking for!
