Swarmlord vs. Overfiend

Within the fray, the Swarmlord and the Overfiend met- the former leaping with incredible speed to avoid the grasp of the Overfiend's immense power claws. Scores of Tyrant Guard sacrificed themselves to shield their charge, but time and again the Overfiend blocked their decapitating strikes with an ironclad arm. Neither leader could overcome their opponent. After hours, the Ork eventually got the better of the fight, landing a devastating punch into the Tyranid's midriff after crushing a Tyrant Guard who tried to stop him. He grabbed the Swarmlord's head in a claw and crushed it. Seizing the monster's body with his other claw, the Overfiend ripped the beast in two.
