Tyrant

The Tyrants (魔王, Maō, lit. Demon Lord) are the major demonic lords from various pantheons in the series. They are one of the few races that are still referred to as Clans in the later officially translated games though they seem to have reverted back to a Race in Devil Survivor 2. Generally they are the major enemy of their respective chief deity. They are the most powerful Dark race, and also one of the most powerful races in general. They're great at everything they do and have no major weakness. Tyrants are basically the Dark version of the Deity race and are just as difficult to fuse. Another Race related to the Tyrant are the Fallen which can be considered a Neutral LND Counterpart.

Devil Survivor 2
The Tyrant race has the Tyranny Racial Skill, which restores MP to the team according to the damage inflicted, along with reducing the combat initiative of the opposing team, reducing their chances of getting initial Extra Turns. Stronger Tyrants have this skill changed to Blood Treaty, which grants an additional option which will triple the power of any recovery or draining ability for the team, including their innate MP recovery. This also means that skills like Drain and Life Drain inflict 3 times as much damage. The Tyrant race is also notable in that every member of this race is Unique.
