Tyrannitar can learn Hyper Beam, a move which (I believe) has been shown to destroy mountains in the anime. Given that Tyrannitar is pseudo-legendary and all pokemon work in fairly similar ways in terms of strengths and powers it can be implied that Tyrannitar has this power.

However

The anime is NOT a reliable source at ALL to determine any kind of battle from. The rules are unclear if not ignored, there are uncontrolled factors affecting outcomes (as would happen with most actual fights, but with 700+ competitors it just muddies stat-tracking), and power is relative. Every time Pikachu enters a new region he resets to level 5 effectively.

The pokedex is, at best of times, a pick-and-choose affair even in the games. Although you can use it to stage an argument it's not a sturdy platform to do so with.
