Termie vs. Avatar

Kul Gilad’s gauntlet slammed into the flaming daemon, and he felt the heat of its molten body through the heavy plates and crackling energies of his fist. Iron buckled and dribbling spurts of blazing ichor oozed from the cracks like light-filled blood. The avatar roared and brought its blazing spear around in a crushing arc. Encased in Terminator armour, Kul Gilad was too ponderous to evade, and he leaned in to the blow, taking it on the curved plates of his shoulder guard. White heat of the hottest furnace imaginable cut through ceramite and the Reclusiarch bit back a cry of agony as he felt the skin beneath char to blackened ruin.

	Kul Gilad batted the weapon aside with his power fist and stepped in to deliver a thunderous hammerblow to the creature’s midriff. ‘All-conquering Master of Mankind, be pleased with this war’s tumultuous roar!’ he sang, his voice booming from the vox-grille of his helm. His fist broke an armoured plate, and magma-hot gouts of its inner fire poured over his fist. Kul Gilad ignored the searing pain and drew back his fist to strike again.
...
	Eventually everything must die, even Space Marines. Time compressed, the motion of his fist moving at the speed of tectonic plates, every spinning warhead ejected from his storm bolter perfectly visible to him as its rocket motor ignited. His fist struck the daemon in the centre of its chest and he unleashed every last iota of his zealous fury and righteous hate in that blow. His fist shattered the hideously organic metal of the daemon’s armour and he felt his arm engulfed in searing, unendurable heat. The daemon’s roar of pain was a symphony to his ears, and he rejoiced that the Emperor had seen fit to grant him this last boon of death. Flames billowed around him and he felt a sickening impact on his midsection.
