Mr. King

Mr. King (ミスター・キング) is the main villain in MegaMan Star Force 3. He is the owner of the King Foundation, a front for his true organization, the Dealers. He intends to have the members of the Dealers harvest Crimson Energy from fallen Wizards which were corrupted by Noised Cards, so that he can enter Meteor G's server, and use its power to control the Earth. Believing humans to be too weak to survive, he feels himself the one fit to rule humanity with his leadership.

Mr. King is known to be ruthless, as he even has his Wizard, Dread Joker engage in combat with Acid Ace so as to harvest the Crimson Energy when they both take each other out. When he escapes to his orbital base, he then uses Meteor G to attack WAZA - Alohaha, and WBG Studio, trapping its staff within Noise Waves, and making the place inaccessible due to interference. His subordinates Jack and Queen Tia confront him, but are shortly held captive. His right-hand lady, Heartless, then turns on him, releasing Jack and Queen Tia and attempts to trap King, but it fails when King reveals to have transformed himself into an EM being, much in the same way Omega-Xis turned Kevin Stelar into one. Mr. King escapes into the Meteor Server, and Jack and Queen Tia follow, intending to use Meteor G for themselves.

At the end of the game, Mr. King appears at the end of the Meteor Server, and fuses with the core of Meteor G to become the Crimson Dragon. His plans foiled, he decides to use Meteor G to destroy the Earth. After the Crimson Dragon is defeated, Mr. King is ejected from the Meteor Server, his fate unknown.
