• Complete Monster (Krosmoz universe):
  • Rushu is the king of the Shushu, a race that takes pleasure in nothing but destruction. Rushu slew almost all his primordial brothers at the beginning of creation to ensure there would be no rule to his reign; regularly murders his own Shushu with casual abandon; and has annihilated all life on his native world of Shukrute, a fact which has him constantly scheming ways to invade the World of Twelve to devastate it as well. Kept only in place by the sacred pact of the gods, Rushu finds numerous ways to subvert or simply outright break the pact, occasionally personally appointing Shushu to wreak swathes of bloody havoc and destruction while routinely tempting souls into becoming more Shushu. Rushu collaborates with the Eliatrope traitor Qilby to gain access to the World of Twelve to start razing everything in sight, his advent upon the world only thwarted by his Arch-Enemy Goultard.
  • Mongrelamus/Medoroziam is one of the original ten Shushu and the only among them who survived his brother Rushu's purge by hiding on the planet that would become the World of Twelve. Medoroziam sought to possess the body of the powerful Iop warrior Goultard by feeding off his murderous anger. Working in conjuction with the sacrier Katar, Medoroziam butchered Goultard's three young children and his wife in order to cultivate Goultard's wrath and thus enable Medoroziam to possess him—turning Goultard's wrath, first, toward Katar. Medoroziam's corrupting influence birthed the noxious "Goultard the Barbarian" personality of Goultard, giving him the ultimate responsibility over all the thousands, innocent or not, Goultard would subsequently slaughter.
  • Wakfu & Islands of Wakfu: Orgonax was the youngest and the prince of the Mechasm people whose heart was stolen by the Eliatrope traitor Qilby to foment war between the two people. Beyond any hope of reason, Orgonax, in retribution, spearheaded a war with the end goal of the utmost destruction of the Eliatrope people, slaughtering countless numbers of them until they managed to escape the Mechasms' wrath. Orgonax persisted his genocidal crusade long after the rest of his people had retired, tracking down the Eliatropes to the planet that would become the World of Twelve and restarting his campaign of destruction all over again. A being of absolute, unrelenting hatred, Orgonax would let nothing—from the murder of the Eliatrope children, to allowing his Lu-Fu servants to suck the Wakfu dry from countless other species merely cohabiting the planet with the Eliatropes—stop him from exacting his revenge.
