Admiral of Atlantis and great warrior, he's the main character of the campaign, and fights to protect Atlantis from the evil ones. In the end he's turned into a god after Gargarensis's defeat and Atlantis' fall.
A centaur hero and wiseman, who's rescued by Arkantos. He's the first to point him to Gargarensis, and help the Atlantinean in his journey. He ends up sacrificing himself against some fire giants after sealing the Nordic Gate.
A warrior-priestess of Isis met by our heroes in Egypt, she's fighting against Kemsyt forces to recover Osiris' body and resurrect the god, and then she follows Arkantos in his quest to the North. In the Titan Expansion she's become Queen, and fights first against Kastor and then the Titans.
The main villain of the campaign, he's a giant Cyclops hero who's blood-related to Poseidon. He's trying to open the Titan Gates in Erebus in order to free Kronos, hoping to receive immortality as a reward.
A God Am I: He has Poseidon's blood in his veins, and he wants to become a fully immortal god at any cost.
Karmic Death: He is cornered on a cliff, all his men is dead, and his arch-enemy approaches him. What does he do? Rather than surrendering, ha jumps on Arkantos, and impales himself on his spear, and then falls to his death. It seems as though the developers were trying to clean Arkantos for any involvement of his death, although he later pretty coldly orders the death of Gargarensis, (actually a disguised Kemsyt), when he is captured and defenseless.
Sinister Scimitar: A simple hook isn't good enough for him, so he uses a whole khopesh blade instead.
The Unintelligible: Like all minotaurs he speaks in grunts and in cutscenes is clear that he can't speak very well.
A follower of Set who's working for Gargarensis. He's magically turned into a Gargarensis deadringer in order to buy the original one more time and is executed by Ajax.
You Have Failed Me: At one point Gargarensis actually says: "You have failed me again Kemsyt", and he repeatedly threatens to perform this trope on him, but although he finally sacrifices him for his own ends, it more like You Have Outlived Your Usefulness.
You Have Outlived Your Usefulness: When Gargarensis finds himself trapped in the Norselands with the gate closed, he needs to get to Atlantis fast. He then uses Skult's magics to turn Kemsyt into a replica of him, effectively ensuring Kemsyt's death and buying himself more time. Overlaps with You Have Failed Me.
A frail, suspicious old man living in Midgard who offers his help to Arkantos, but is eventually revealed to be Loki's avatar. He also appears in the campaign focused on Brokk and Eitri.
Arkantos' son, he's leading the Atlantinean to a new age and, guided by Krios, decides to accept the cult of the Titans and attack the other gods. He ends up releasing several Titans from Tartarus and atones himself by releasing Gaia to defeat Kronos.
Ascended Extra: He appears a few times as a child in cutscenes of the Fall of the Trident's campaign, but doesn't have any importance in the plot. Ten years later, as an adult he is the hero of the Titan's campaign.
The King of the frost giants mentioned in The Fall of the Trident. Along with his loyal subjects he joins forces with our heroes to stop the Nordic Titan from destroying everything. He also appears in The Golden Gift, as a minor antagonist.
An Ice Person: He can even freeze Titans solid for a while, and in The Golden Gift, he repeatedly freezes anyone crossing the pass leading to his base, or approaching him.
Heel Face Turn: After hearing of Arkantos' victory over the forces of Gargarensis, he decided that humans were worth something after all, and left his evil ways in order to forge a kingdom for both humans and giants.
Filler Villain: His appearence in The Golden Gift. Ha has no relation to the plot or characters of the story at all, he just obstructs Brokk's path to the mines, and his forces must be defeated.
Large Ham: Namely in The Golden Gift. "You tiny men stay out of MY PASS"
Offstage Villainy: Mentioned to be a vicious and bloody tyrant in the original campaign.
The Other Darrin: In The Golden Gift, he actually appears in person, but as his finished model is only present in the expansion, and the campaign where made both for people with and people without the expansion, he is instead represented as a Frost Giant of Thrym.
God of the Sea and defender of Atlantis, he's the god worshipped by both the Atlantineans and Gargarensis. Revealed to be the Bigger Bad behind Gargarensis, he's envious of Zeus' power, so he wants to free Kronos and use him against the other gods.
The Beastmaster: His divine power summons a giant runic stone that attracts all the animals nearby.
The Mole: His god power allows you to turn an enemy soldier into this, allowing you to see what he sees. Also, in the campaign, when he is disguised as Skult, he pretends to be on Arkantos' side, only to make him lose time and men on fighting the clans.
The Sky Titan and father of Kronos. He doesn't play a role in the Expansion at all, but it is implied that he is just as evil as his son, considering that only Gaia is good among the Titans, and that some of the enemies worship him.
Kraken: Njord's mythical naval unit, capable of one-shotting ships.
Our Giants Are Bigger: Skadi has the Frost Giants (MightyGlaciers who can freeze their enemies), Njord has the Mountain Giants (powerful and slow creatures who deals extra damage to buildings) and Baldr has Fire Giants (flaming monsters with ranged attack). If you choose Hel, you can hire all three types of giants, but without their individual upgrades.
