Forty thousand years ago, a
caveman warrior named Eshu was cast out of his tribe in what is now northern Asia after he killed another caveman against his tribe's laws. He wanders the Earth and is soon
psionically called to the beacon of an alien ship. Eshu is captured by the alien
Plodex, who experiment on him and repeatedly dissect and reassemble his body. His intelligence increases over the years until his mind and body are developed to the peak of perfection. After some time, Eshu learns to access the ship's systems, allowing him to escape. Now calling himself the Master of the World, he captures Alpha Flight after luring them to the Arctic. The Master of the World is confronted by
Namor and the
Invisible Woman, during which his starship is destroyed. He escapes his ship via a submarine. Using his knowledge of the alien technologies, the Master gains control of
Marrina Smallwood and her Plodex mate. The Master causes Marrina to revert to savagery and captures Namor and Alpha Flight's
Puck. However, Puck tears the Master's helmet from his head, severely injuring him. The Master's submarine explodes, thwarting his plans to dominate the world. The Master escapes and enters a state of
suspended animation, from which he is freed by
Llan the Sorcerer. His next plan is to take over the
Canadian government under the alias Joshua Lord, exploiting the chaos caused by the Super Power Registration Act. The Master also reforms
Omega Flight to stop Alpha Flight from getting in his way. The Master finds
James Hudson entrapped in a dimensional limbo. He resurrects Hudson as the Antiguard, intending for him to kill Alpha Flight. Guardian, with the help of his wife
Heather Hudson, breaks from the Master's mental control. The Master seemingly kills himself to avoid being imprisoned. The Master is the founder of Strikeforce One, consisting of Amazon (a clone of
She-Hulk), Behemoth (a clone of
Hulk), Demi-God (a clone of
Hercules), Dragonfist (a clone of
Iron Fist), Knight Errant (a clone of
Black Knight who wields a flaming sword), She-Cat (a clone of
White Tiger), and Stinger (a clone of
Ant-Man). Strikeforce One proves to be difficult opponents for
Heroes for Hire, who turn the tide against them. The Master escapes while Strikeforce One is presumed dead. The Master seemingly dies again, at the hands of
Warbird, when she kills him so that the
Avengers can use his weapons to help attack
Kang the Conqueror's forces. Although Warbird requests that she be tried for the Master's death, a tribunal headed by
Captain America concludes that there would be no punishment, as Warbird was acting out of necessity. During the "
Fear Itself" storyline, it was revealed that Master of the World was behind the motives of the Unity Party, which had been targeting Alpha Flight. When Alpha Flight escapes from
Department H, the Master forces Vindicator and Department H to assemble Alpha Strike (consisting of
Persuasion,
Ranark the Ravager, a
Wendigo, and a brainwashed Citadel) to spread the Unity program and take down Alpha Flight. At the end of the
Alpha Flight 2011 series, he is seemingly killed in a battle with Alpha Flight. During the "
Civil War II" storyline, Master of the World resurfaces and assumes the alias of Phillipe Beaulieu, working for the Board of Governors for the Alpha Flight Space Program representing Canada. Master of the World plans to corrupt the evidence in order to isolate Captain Marvel and gain control of the justice system. When it is discovered that
Aurora was framed and Captain Marvel confronts Phillipe Beaulieu, he sheds his disguise. After obtaining
Thundersword's sword, Master of the World battles Captain Marvel until Thundersword appears and reclaims his sword. ==Powers and abilities==
