Ballard Eberusu III

"The Red and Rainbow Miraculouses have a main purpose to be one of the strongest...therefore It's my duty to grab them to rule this world, recreating a new society in my image!"

- Doomsday

 is an antagonist of the Miraculous Red series and is the overall main antagonist of the series. With the Gold Knight Miraculous inhabited by the kwami Chevalier, he can transform into the supervillain Doomsday granting the power of Golden Destruction, a power where it is the opposite of Red Aura and the power to akumatize anything and anyone.

Doomsday's main control is to take all of the miraculouses for himself to rule the world and defeat and annihilate all the heroes to make a "perfect" world.

Personality
As Doomsday, Ballard's personality seems to be a strange mix of courage, sadism and malevolency, and as well as high intellectual capacity. These combinations of his personalities together gives him off as one of the most dangerous villains in the series. He also shows somewhat a cunning personality usually giving his akumatized villains the information provided to take both the Red Miraculous and Rainbow Miraculous to complete his world dominance, but he will also go even beyond to the point where he will want to take other people's miraculous as well.

He is also exceedingly power-hungry and greedy, aiming to stop at nothing to defeat Red Noir once and for all. His hunger for power led to some of the akumatized villains/sentimonsters to be willing to take his orders as he will punish them for not following his order or to take away their power so that there problem could not be fixed.

However, he can make it up to his akumatized villains or sentimonsters by offering constructive criticism and encouragement to go in at any hero that attempts to stop them in the process, especially if Red Noir is present in the battle to take their akuma away from them.

As Doomsday
As the supervillain Doomsday, Ballard grants superhuman abilities including strength, speed, and durability. He gains the Golden Sword, a giant sword weapon he can use if he wants to do battle, and has a superpower called Golden Destruction, a destructive power that's the complete opposite of Red Aura that can destroy anything in the process and is capable of creating Akumas or Amoks to send out and possess anyone who shows true negative emotions to take control of them. Golden Destruction is capable of also creating vortexes to either reduce anything to nothing or to absorb and nullify anything to become stronger, and the free will to control akumas as an attack, even if it was Hawk Moth's akuma, Doomsday can still control them as well, examples would be creating alot of them to surround the foe and drag them in the ground into a giant ball that suddenly raises up above him and explodes with the foe inside of it.

Similar to Red Aura, Golden Destruction can also create energy-like projectiles to cause destruction by either creating a giant ball of energy or use it on himself to enhance his powers.

Trivia

 * Doomsday takes inspiration from Marshall D. Teach, aka Blackbeard from One Piece with the following:
 * Both have the power to cause destruction and can nullify things out of existence to empower themselves to be stronger.
 * Doomsday used to look more slimmer and showed eyes, however he was redesigned to be a much stronger and much taller golden knight and to look more menacing.
