Arch Duke Deimos, the Wheel of Reincarnation, is the Mad Scientist who reigns over the human world. He created the humans of the world, but turned them against the Demi-Gods and Proteus, eventually sealing them away, so he could have the world to himself. Repeatedly sending people to die fighting Shadar and not caring about their lives, Deimos does the same with Slade and Sharn, later declaring them traitors when they discover the truth. He also creates golems out of human corpses, then treats his creations coldly, among them being Orion, implanting a device in him that allows him to control Orion and force him to slaughter people. When he sends a trio of golems after Slade and one of them dies, he kills Fianna for failing him and assaults Sarius's mind for objecting to it, later sending him to die against Slade. He then attempts to have Iris, his own daughter whom he exiled with Slade, stuffed with energy to use her as a weapon against the Demi-Gods. In the fight against him, he devours the souls of his own Druid helpers, and even when killed, he drives Abel insane and sends him to destroy the world, then comes back and tries to use Iris and Slade to resurrect himself.
Apollo of the Absolute Will is the leader of the five Demi-Gods. Following his abuse at the hands of humans, Apollo desired to wipe out humanity, and manipulated the abused child Abel into sharing his worldview that humans are all "failures" that deserve death. Rebelling against his father Proteus, Apollo imprisons him inside the Firebrand sword, then has him possess Kahn and sends them down to massacre humans, wiping out a good chunk of the world population. In the present, he sends his siblings to destroy several towns and massacre the people within, and tortures his sister Arianna for taking too long. He later personally destroys the city of Darnia, killing everyone within, and taking the souls of the inhabitants while wiping away their memories of being human. He creates Averron as his utopia using the souls, some of which are turned into the crystals powering the place, and has Slade imprisoned and sentenced to Electric Torture while he tries to convince Khan, a fellow Demi-God, to join him in creating a "perfect" race to replace humanity, despite knowing his rhetoric is nonsense.
Evil Is Cool: Shadar is a nearly invincible badass villain and being impressive even without full power.
Ensemble Dark Horse: For some players, Shadar gets more likes than other characters.
That One Boss: Arianna is the single hardest of the Demi-Gods to defeat, mainly because her attacks are simultaneously hard-hitting, group attacks AND hand out debilitating status effects like candy, along with attacks that can sap mana. It is very easy for her to incapacitate the entire party as a result.
