Lairtrum will bash their iron heads together to compete for territory, until one finally collapses. Their jaws are strong enough to allow them to eat large chunks of rock and metal.

Thanks to its gargantuan jaws, which could shred thick metal plates as if they were paper, it was invincible in the ancient world it once inhabited. When two Lairtrum meet in the wild, they fight for territory by bashing into each other with their steel bodies.
