Red Sand Double Kill

[Setting Notes] Primarch No. 12, Angron, rebelled against Khorne and spent his life killing all things and destroying humanity; Primarch No. 21, Agron, is his twin brother and has been absolutely loyal to the Empire of Man from beginning to end. Agron's exclusive primarch armor is based on the parallel fallen version of Angron's demonic heavy armor, purified, expelled, and reforged by himself. The two brothers fell into Nuceria at the same time, and were implanted with the cruel Butcher's Nail. They endured severe nerve pain for the rest of their lives. Their physical brute strength, fighting madness, and killing talent were all from the same source. Agron completely removed all the chaotic and corrupt patterns from the armor, and recast it into a solemn silver-gilt armor, engraved with the Broken Shackles emblem, and armed with double thorn power fists and a giant chain axe. He commanded the 21st legion of the "Red Blooded Flail Guards". The entire army was equipped with chain axes as standard. They followed the World Eaters' violent charging tactics to kill the enemy thoroughly and without mercy. The ferocious momentum on the battlefield was no different from that of the fallen World Eaters. Even though the Butcher's Nail continued to arouse bloodthirsty rage, he and his soldiers adhered to the absolute bottom line, pushing away friendly troops with only the back of an ax and fists, protecting civilians, covering wounded soldiers, and never killing innocents indiscriminately. The Horus Heresy broke out, and Angron and his World Eaters completely degenerated into minions of Chaos. Wearing a purifying and ferocious armor, Agron guards Terra with the ultimate violence of the same origin, and defends the order of the empire with the most ruthless killing. He is the most unique and loyal killing king in the 40K universe with the ultimate contrast between good and evil.
