Unknown Dictator (Alvedrez)

Unknown Dictator (未知の独裁者 Michi no dokusai-sha) also known as The Imperial Child of the Machine World is one of five new longinus and a powerful sacred gear. It takes the form of of a crown of thorns that is wrapped around the user's head. It is currently wielded by the leader of the new Hero Faction, Theseus. It is featured in Highschool DxD: A Hero's Welcome.

Abilities
Unknown Dictator is a longinus-tier state-change Sacred Gear that allows the user to gain magical power and strength from those loyal to them. These loyal people needn't be human with devils, dragons, gods, even beings created by other sacred gears counting as "loyal followers". The larger this sum of followers is, the stronger the user becomes until they begin to manifest all sorts of strange powers. These powers can simply be healing, or they can be something as complex as space manipulation. Some of the biggest leaders in all of history wielded this longinus, one of whom was the original Julius Caesar of Rome.

The strength gained by each individual follower depends on the strength of themselves. With higher tier beings giving much more energy to the user than simple humans. So far, there has been virtually no cap to the amount of power a user can accumulate so long as they have the right amount of people.

Forms
Unknown Dictator most often takes the form of a crown of thorns, not unlike the one put on Jesus's head when he was crucified. Despite this, the crown is not considered one of the holy artifacts but is instead considered something of a replica.

Balance Breaker
The King Commands It (王の命令それ Ō no meirei sore) also known as The Sun Will Never Set on This Empire is the natural balance breaker of Unknown Dictator. It is only usable once the wielder accumulates a significant amount of energy, but once they have enough they can activate immediately. In this form, the user gains a fiery halo around their head and, for a period lasting no more than 10 minutes, the commands given by the user are absolute, and must be followed.

This ability is potent enough to force even the likes of Dragons to submit to the user's will. The wielder can have his foes turn on eachother, give up their magical power, hand over their sacred gears, and even force them to commit suicide. This ability can also be used to buff one's allies, ordering them to heal or become ten times as strong and even commanding an impenetrable barrier to surround individual soldiers.

Weaknesses
The most glaring weakness of this sacred gear is its reliance on loyal followers. If the user cannot gain enough people under them as subordinates, or if they lose the loyalty of their current followers, all the power accumulated is drained immediately. This can be potentially deadly if the user is in the midst of performing a highly draining spell or they're in an extremely close fight. It is rumored that Julius Caesar fell prey to this weakness as, at the end of his life, those once loyal to him had secretly turned and assassinated him.
