Archimedes is one of the playable commanders in Tooth and Tail. He leads the Civilized faction, represented by the color yellow, and symbolic of an Oligarchy. He was one of the forefathers of the Lottery System that is currently in place, which chooses who is slaughtered to feed the masses. However, over time, the Civilized became more and more corrupt until none of the Civilized ever ended up being chosen in the Lottery. Despite his disdain for the other factions, he is very willing to recruit turncoats to his side. Archimedes alleges that he was the person who brought the toads and the snakes into the Civilized ranks, although whether or not this is true is debatable.
- Although Archimedes is the playable character for the Civilized, he is only considered its left hand with the actual leader, and right hand of the Civilized, being Sage Marro.
- Archimedes and the Civilized were once planned to have a wine-like and later on purple faction color. These ideas were both scrapped, as people saw them as not fitting for the character.
- Archimedes is voiced by Scott McNeil
- Archimedes is partially inspired by Grigorij Rasputin
