Another MLP oc of mine. :)
(Be warned i may have horrible spelling.)

Of course you can tell, he's a shark pony.
He wasn't always a shark pony, he used to be just a regular earth pony.
Scientist had made a syrome that could transform any species and give them genes from another species.
Razor tooth was one of the few ponies picked for the experiment.
as they used it, he started getting thirsty a lot, one time he tried to eat a cow.

Well i'll add in the rest of his backstory on my DA account.
