Sigma/Archie Comics

This article is about Sigma in the Archie Comics series.

Mega Man 8: Redemption
The Reploid Sigma was created in the year 21XX and first appeared in the story "The X Factor - Part 2" from Mega Man issue 35, where he was the leader of the Maverick Hunters for two months, having already his fight with Zero, and also has a talk with X regarding the possibility of him joining the Hunters.

Mega Man 9: Dawn of X
In issue 39, Sigma appears again after the Wily Walker goes on a rampage, dispatching Zero and Vile's Hunter companies to challenge the Walker while he goes to Dr. Cain for information. Upon learning where on the Walker its chemical weapons are located, Sigma joins his two subordinates and X in confronting the weapons platform, unaware that the addition of his presence prompts the Wily Walker to ready its chemical weapons payload. After the Walker is taken down, he congratulates them on a job well done. However, he agrees with Vile that Reploids are superior to humans in many ways, which, while he says is why it's up to the Hunters to protect humans, foreshadows his eventual change to a Maverick.

After the Wily Walker incident, Sigma became a Maverick and also the leader of all Mavericks. While X succeeds in stopping him and his original body is destroyed, Sigma lives on as a sentient virus and became the greatest threat for the Maverick Hunters and the world.

Worlds Unite
Sigma is featured as the main villain in the Worlds Unite crossover event linking the story lines of the comics Mega Man, Sonic the Hedgehog, Sonic Universe, and Sonic Boom. Some time between the events of Mega Man X7 and X8, the Maverick Hunters launched a massive assault on Sigma's latest fortress with the intent of wiping him out for good. However, he had also discovered the Genesis Portals and intended to scout out some worlds to take over, with the ultimate goal being to become a god over all of the multiverse. He ultimately settled on Sonic's world, as he decided it was easiest to conquer due to Dr. Eggman's abuse of the Deadly Six making them very easy for them to turn to his side. He then disappeared through one of the portals just as X came in to end him, although not before cryptically hinting that he had only just begun his conquest of worlds.

After traveling to the Lost Hex in Sonic's universe, Sigma uses Orbot as a host and makes a deal with the Deadly Six, breaking the Cacophonic Conch to free them from Dr. Eggman and forcing the doctor to create a new body for him, "Sigma-1". After Sigma shows more things for Eggman to create, he complains that working on his body was tiring and it is to much work for only one person. Sigma agrees and captures Dr. Wily to assist him, and both doctors create for Sigma armors that allows him to control the Deadly Six, the Unity Engines, and turn a captured Sonic and Mega Man into Sonic Man and M'egga Man.

Short Circuits
Sigma appears in several Short Circuits, beginning in issue 35 where Mega Man X offered to trade him for Mega Man's nemesis of Dr. Wily after his counterpart complained that Dr. Wily was the worst person he ever encountered. Upon seeing Sigma, Mega Man immediately took back his complaints about Dr. Wily. He returned for Issue 39's strip, where he extolled his pet Velguarder as a robot dog superior to Rush and Treble.
