I think I may have noticed a error on here cause the HA for Tyrunt is different on the game then it is on here. According to your website tyrunt's HA is rock head, so why is it on the game the HA for it is sturdy instead?
That's a mistake on here; Tyrunt should have Sturdy. A Tyrunt with Sturdy will evolve into a Tyrantrum with Rock Head.
Serebii - Tyrunt
Bulbapedia - Tyrunt
