Sigma from the Mega Man Zero franchise walks down the street. The hears something flying towards him and looks behind him. He catches it and sees that it is the head of Zero. He drops it and looks around to see who threw it. Then from in front of him, he sees Thanos, in his Infinity War design, walking out from a portal, which closes behind him. He eyes the robot down and shows him every Infinity Stone in the Infinity Gauntlet. Sigma then rushes at Thanos.
Bullet: BEGIN THE BLOODSHED!The Reality Stone glows as Sigma attacks Thanos. The hits from Sigma pushes Thanos back. But he uses the Power Stone to punch him hard enough to send the robot through a skyscraper. Thanos then chases after him by walking into a portal. Sigma stands up after landing on top of the tallest skyscraper. Thanos appears behind Sigma and punches him as hard as he can. Sigma slashes Thanos in the cheek with his Sigma Blade. The mad titan wipes the blood of his face and glares at the robot. He then uses the Space Stone to pick up a building. He pulls the buildibg apart and throws it at Sigma, who dodges the vricks. Though some bricks do hit and dent him, Signa just powers through it. When Sigma was clowe, Thanos activated the Time Stone to recerse Sigma's place back so that he is pelted by all of the bricks that were thrown at him. After shaking the dust off himself, it is shown that he is heavily damaged. Sigma rushes at Thanos again and begins to slash at him some more. It was not until Thanos's top was sliced to shreds and left him shirtless that he kneels down. Sigma then impales Thanos through the heart, but then the Reality Stone glows again and Thanos disappears, showing that the Thanos he fought was a fake. The mad titan then jumped through a portal and pinned Sigma to the ground before wailing on him with a flurry of punches. Thanos then stands up and smirks at the defeated Sigma. Then Thanos snaps hus fingers, making Sigma turn to dust. Thanos then chuckles before opening a portal and walking away.
