The V. Rex charges out of the jungle biting down on a Diabloceratops' back killing it instantly. The Diablo herd runs for cover as Rex starts eating his kill. He is alerted by another another animal's roar at the other end of the field and, looking up, sees his old foe, Torgosaurus. He roars back accepting the challenge. He knows this will be his last encounter with Torgo so he's willing to do anything to be apex predator. They blast towards each other at full speed (50 mph for V. Rex, 65 mph for Torgo). And they collide mouths agape, Rex going for the belly, Torgo for the base of the head. They then break away and begin circling each other looking for a weakness. Rex spots a dewlap on Torgo's throat and lunges for it. Torgo, realizing this, rears up and slams a three clawed hand into the Rex's face wondering how this thing can be so aggressive. Torgo then, seeing his chance, lunges and bite onto Rex's neck. Rex, bellowing in agony, slams his tail into Torgo's face repeatedly. Torgo then jerks his head to the right, flinging Rex 50 feet through the air but forgets to let go and loses some teeth at the expense of paralyzing the Rex. He then walks over, places one foot on his foe's head and crushes it killing him. Torgo lets loose a deafening roar in victory and begins to feast on his foe's corpse.
