The power to
have an incredibly powerful bite. Variation of Natural Weaponry.
Enhanced Jaw Strength
Hyper Jaw Strength
The user has particularly strong bite, either because of sharp fangs/teeth, strong jaw-muscles, unusual jaw-structure (mandibles of insects, beak, etc.) or some other reason. Exactly what they can bite depends on the jaw-strength, resilience of their teeth/bite-surface and their shape.
Jaws/teeth can break on hard substances.
Must be abler to bite, making large/flat surfaces a problem.
Teeth/mouth may still be sensitive, and may have to be careful not bite down on anything potentially harmful or dangerous.
