first Overlord
The son of a disgraced Duke, Lord Gromgard found the Overlord's armour in a blocked-off room after receiving a mysterious glove and his Brother and Sister had a row. When they slammed the doors, he found the throne room, where he became the new Overlord just like his great uncle, The Black Baron, with Gnarl and his Minions by his side. Overlord: Dar
second Overlord
The Second Overlord was one of the greatest Overlords known to have existed. It is unlikely, however, that he is actually the second successor in the lineage. Indeed, according to Gnarl, he has seen at least four masters destroyed. It is possible, but unlikely, that he includes the so-called "Second Overlord" in his list while excluding the 8th Hero, who was trapped alive within the Infernal Abyss.
third Overlord
The Third Overlord is the third known holder of the Overlord's mantle and fiercest enemy of the Seven Heroes. He once led a ruthless quest for vengeance and conquest that made him the undisputed sovereign of the world for some years. He had as many names as the lands he had conquered, as many titles as the enemies he had slain. But before his rebirth in darkness, he was simply known as the Eighth Hero, a heroic companion of the legendary Seven Heroes, who contributed more than anyone else to the downfall of the Second Overlord. He was subsequently betrayed by his former comrades and left for dead in the ruins of the Dark Tower. Currently, he resides in the Infernal Abyss, having replaced the Forgotten God as the God of the Abysses, and commands the Wraiths.
fourth overlord
The Fourth Overlord is the fourth known holder of the Overlord's mantle and fiercest enemy of the Glorious Empire, who led a ruthless campaign of conquest that made him the undisputed sovereign of the world for some years. Traveling widely around the world in search of new lands to subjugate, the Fourth Overlord has earned a number of epithets and aliases from those who have suffered the effects of his vile actions. In Nordberg Town he was known during his youth as the Witch-boy, for there he experimented his first nefarious magical powers against the other children of the city (however today only his first mistress, Kelda, dares to call him this way, and only by using it as an affectionate nickname). In the Elven Resistance he is the Scourge of Nature, following the destruction of the Nordberg Sanctuary, by his hand, and the agonizing death of all the creatures who lived in there. In the Glorious Empire, he is the Demon Lord of Nordberg, following his bloody conquest of the snow-covered city of Nordberg Town at the head of a demonic-looking minion army. When he was a child he was also jokingly called by his minions The Overlad.
The Seven Heros
The Seven Heroes were a brotherhood of seven champions and heroes of the various species of the known world, gathered together by the great magician simply known as "The Wizard" in order to defeat the Second Overlord and end once and for all its evil rule over their lands. By the beginning of the game, however, the Heroes have sunk into depravity and become the main antagonists of Overlord. However, though they are most commonly referred to as seven, there were originally eight of them...
velvet
Velvet is was ex-sister and Rose is was good a Sister the second mistress encountered in Overlord. She is the younger of the two daughters of the Wizard. When the player meets Velvet, her sister Rose is present and the player must then choose which of the two sisters they wish to have as their mistress.
Rose
While helping refugees of the Plague in Heaven's Peak, Castle Spree came under attack by bandits, led by someone who seemed to be Kahn and Jewel,. She was saved by the Third Overlord, who drove the bandits from the castle, and afterwards, she joined him to be his mistress.
Gnarl
Gnarl is the aged and much-feared Minion Master of the Minion horde, loyal servant of Darkness, advisor and personal right-claw of many Overlords throughout history. By his recurring appearances in all the Overlord games, it can be assumed that he is possibly the first minion ever spawned. The only other minion almost as old as him is Giblet, which he mentions when touring the fourth overlord. He is very wise and he seems to know many languages. This is demonstrated when he translates the gnome communication when they declare war on the Fourth Overlord, and also when he translates the mumbles of the Silent Order to the Third Overlord. He also has a greater vocabulary than most minions, as he is to be smarter than the minions and has the same intelligence, if not more, than the overlord himself. He has a glowing crystal hanging from a wooden stick, strapped to his back. He uses the crystal as a lantern/illumination device, and judging from the glow, it could be a soul or Life Force, but it is currently unknown what it actually is. It is also unknown how he became more aware than the rest of his fellow minions, but it's suspected that he could be an overlord trapped in the body of a minion, and this is what causes him to betray the overlords and cause their downfall
Brown Minions
Browns are the basic minions that you start out with and are subsequently the most versatile of all the minions. Brown minions are born fighters and will gather Minion Equipment that will help them in battle (such as swords and armour) as well as things that have no relevance in battle (like pumpkins to wear as hats or Melvin Underbelly's crown.) They can sustain the most damage and can hold their own in a fight. They can not go through water, fire, or toxic gas however, so whilst it is important to always have some with you, it is generally a good idea to have some of the other minion tribes with you as well. Also they, unlike the other minion tribes, do not have tails.
Red Minions
Reds are weaker and less equipable (they still do take equipment for themselves though) than their brown cousins. They have a ranged attack that can be very effective if used correctly. While this minion clan does not boast a large health pool, they possess the invaluable ability to be immune to fire and absorb flames. If paired with stronger minions, like browns, the reds will provide fire support to their fellow minions. They are best used on humans, halflings, Ruborian Raiders and any other creature that fears fire. If enough reds target an enemy, the enemy can catch on fire and take periodic fire damage that lasts until the flames wear out or the target dies.
Green minions
Greens are slightly stronger than reds and are valued for their stealthiness, being invisible if still, their ability to pass through poison gas and absorb poison clouds, and their immunity to poison attacks, but they have poor hygiene as they have a foul smell of rotting flesh. They turn invisible to your enemies if posted at a guard marker, causing enemies to walk by without noticing them, until given the order to attack or when the enemy comes too close, which then the Greens attack automatically by jumping onto their backs if possible. Greens can do more damage than browns but only if you can attach them to your opponents back (works best on large enemies) in Ovelord 2 they have lost their automatic backstab attach (unless posted at a guard marker), requiring you to manually target the back of said enemy. They are also very quick as Gnarl commented on the fact the greens got distracted in the Minion Exodus, "We blinked and they were gone."
Blue Minions
These are the weakest of the Overlord's minions. However, they are the only Tribe that is able to swim where all other minions would drown ("in rather amusing ways", according to Gnarl). They can also revive dead minions (as long as they are in one piece). These are the only minions that will not attack an enemy without your order, but they also have the advantage of magic attacks allowing them to attack ethereal enemies, like wisps and ghosts. They can "auto-resurrect" if placed on a guard marker near the place of their fellow minion's death. However, they are unable to truly attack enemies with a large health pool such as Empire Soldiers and Gargantuans.
