Their hooves are thicker than most manmade materials, and able to smash diamond as if it were sand. Presumably due to this, their horns are highly sought after by poachers and the like.
They also can leap great heights over cliff-faces and rocks, due to the males having to always train their stout legs when competing for females of their herd in a contest to decide who the alpha male shall be.
Moostrike are very aggressive and generally very protective of themselves and/or herd. However, they do not mind the company of other Pokémon from time to time.
Moostrike tend to live in mountains usually far from the reach of humans, and because of this, they are considered to be very antisocial Pokémon, especially considering their negative attitude and instinctively protective nature they hold over their herd and themselves.
Moostrike are fierce and aggressive Pokémon, despite their appearance and usual portrayal. Males are known to fight to near-death over territory and mates.
