History
After the Quiet Council of Krakoa was compromised by Mr. Sinister, they gradually began spreading their corruption to the rest of Krakoa and the world at large, slowly taking over the planet from the shadows.
Doom eventually grew suspicious of the Krakoans, and sought out his old ally Namor to form a united front against Krakoa. Unbeknownst to Doom, Namor had already been compromised, and murdered Doom. Doom was replaced with a clone under Krakoan control, while one of his Doombots joined the Orchis resistance.[1]
