The Sugar Man was in charge of the Seattle Core, a slave camp that helped power North America during the Age of Apocalypse. This happened to be the same slave camp that held Illyana Rasputin, the sister of Colossus. As leader and teacher of the next wave of X-Men, Colossus was asked by Magneto to retrieve his sister so Magneto could have access to her reality-traveling powers - power that had become extremely rare in the Age of Apocalypse. Colossus and his students, the team called Generation Next, broke into the core to rescue the young girl.

During the rescue attempt, Sugar Man discovered two of Colossus's students and ordered their immediate execution. With their cover blown, the young mutants fought desperately to survive. It appeared the Sugar Man was destroyed by a psionic bio-blast from Chamber in the opening moments of the battle but that was not the case. Sugar Man shrunk himself down and hid in Colossus's boot as the X-Man tried to get Illyana to safety.

Following the Sugar Man's apparent death, a huge battle broke out in the Core. Colossus's students fought bravely but were apparently wiped out by the Sugar Man's guards. Colossus was able to escape with his sister, not realizing the miniature passenger he carried along in his boot.

Not wanting to give away his position, the Sugar Man remained in Colossus's boot until the final battle in Apocalypse's headquarters. Realizing things were going poorly, Sugar Man dove into the M'Kraan Crystal and traveled back in time to the moment the Marvel Universe and the Age of Apocalypse split. He entered the Marvel Universe and made his way to the island nation of Genosha. While there, he took control of the island. He used his knowledge of the genetic-altering Infinite process to create the mutate slave population that thrust Genosha forward as an industrial giant.

Since then, Genosha has fallen apart. The island nation is rebuilding following a brutal attack by Sentinels controlled by Cassandra Nova. The attack killed close to 14 million mutants. Sugar Man survived, but recently Callisto killed him, in self defense.
