The Underlords
- God of Evil: He wears the title proudly.
- Jack of All Stats: Has no particular specialization when it comes to how he operates.
- Silent Protagonist: The only Underlord who doesn't speak often, if at all.
- Super Mode: In the final two levels of the game, Oberon uses the power of the Kenos to boost his mana reserves and how fast they recharge, double his default Worker population, and disrupt the mana pools of other Underlords.
- Technicolor Fire: His dungeons are themed around green hellfire, with a rocky heart as his cores.
- Defector from Decadence: Turned his back on the Underlords before they were sealed away.
- Defiant to the End: Even after his core is destroyed, he merely pities Oberon's inability to see what Mendechaus has planned.
- Heel–Face Turn: At least, as far as objective alignment is concerned.
- Evil Is Visceral: His dungeons are fleshy and red, and his core is a mass of tentacles.
- Villainous BSoD: Spends a lot of his time undergoing this, as his only core left is severely weakened. He also claims to remember another life where he was nowhere near as heinous as he is now, and is not taking it well.
- Drunk with Power: After stealing the Kenos for herself, she whisks it away to her home realm and attempts to attune with it, allowing the power to go to her metaphysical head.

- Dual Boss: Aside from being part of a four-lord free-for-all, his dungeon is unique in that he has two separate cores controlled by his divided consciousness.
- Fatal Flaw: Korvek's self-sabotage means that while he has powerful minions and a fortified position, he rarely spares the time to branch out or press his advantage.
- Literal Split Personality: His mind is so fragmented that each core he sets up is controlled by separate parts of himself that torment him constantly, to the point where his core is a circle of incomplete statues.
- Stone Wall: His methods are very defense-oriented, entrenching himself in a singular area, and making no effort to move until there's no other option. By then, however, he's usually trained his monsters close to the max level.
- Bling of War: Her dungeons are lavishly-decorated, with her core being a giant diamond orbited by gold rings.
- Collector of the Strange: She's dedicated herself to having as vast and wide a collection as she can.
- Conspicuous Consumption: She's just as eager to throw her money around as she is to gain it, and typically has large amounts of Gold Sentinels on hand, alongside choosing the gold-focused Colossus as her first Titan the moment she's able to.
- Fatal Flaw: Her need to have everything to herself presses her to attack other Keepers in a Mêlée à Trois to try and have their resources. As a result, however, she tends to spread herself and her minions thin, and it can be easy to starve her out since all of her resources are fueled by gold.
- Lava Pit: More specifically, moats of molten gold.
- Zerg Rush: Has a lot of monsters under her thumb, and will utilize them at a moment's notice.
- The Caligula: During the story mission he appears in, you can overhear him slapping an imp to death and valuing it as more important than any actual strategy. He likes to talk a lot about conquest and bloodshed in general, in fact.
- Evil Gloating: Will do so whenever given the chance, and sometimes when he hasn't been.
- Fatal Flaw: His reliance on quantity over quality, combined with his penchant for attacking the first outcropping of your dungeon he can find, means that he can be manipulated into a trap.
- Leeroy Jenkins: Is often the first to attack when it comes to a battle.
- Our Liches Are Different: Primarily specializes in undead, with a core that looks like four skulls fused at the backs of their heads, and a penchant for lining his defenses with Wells of Souls and Bone Chillers.

The Augres are descended from an ancient sect of Ogres who revered the unparalleled Dwarven mastery over metalwork so much that they began to worship Torag, Dwarven God of the forge. They then began to reshape their lives around metallurgy and the creation of intricately designed machines. After some time, these creatures became so enamored with expertly crafted metalwork that they began to augment themselves with their creations by physically grafting metal and machines to their bodies to improve their skills in battle and at the forges where they work.

- Expy: Of the Horned Reaper from Dungeon Keeper, being a large, red-horned demon that thrives in melee combat, and is even said to be descended from a race of "Red Reapers". Thankfully, it hasn't inherited the Horned Reaper's nuclear-grade temper.
