A powerful shockwave spanning through the entire canyon was created from the collision.
Rex got headbutted by the charging wild cat that is burning its life force just for this one attack, it realizes that it won't be able to win against the combination of Rex and Devo.

The shockwave ripped the ground out of its crust,
