X Foundation

The X Foundation (エックス財団) is a mysterious organization headed by Mr. X that appears in Mega Man 6.

History
Little is known about the X Foundation, except that the billionaire Mr. X is its leader and sponsors the World Robot Alliance and the First Annual Robot Tournament as part of his plan to conquer the world. Mega Man faces Mr. X in the X Foundation Headquarters to stop him. It is unknown what happened to the X Foundation after the game, but it can be assumed that it went out of business after Mr. X's defeat.

Mega Man (Archie Comics)
The comic series features the X Corporation as a mysterious group led by Mr. X. Their membership includes both men and women, who wear black uniforms and masks decorated with white letter Xs. Led by Madam Y, a group of them traveled to the ruined Wily Castle after the battle between Mega Man and Gamma. After searching, they found an injured but still alive Dr. Wily and transported him away from the ruins as part of their master's plans. It is revealed in Issue 49 that their agenda, similar to the Emerald Spears and Xander Payne, was to have humanity realize their error regarding their reliance on robotics, and that they saved and recruited Dr. Wily specifically for this reason as their leader had "seen the future." They also took over the remains of the Wily Castle and Gamma.

Mega Man Megamix
Mr. X appeared and poured his seemlingly limitless funds and talents into reestablishing the Global Robot Union as the World Robot Alliance.

Rockman 6 manga
