Ultron vs Sigma - Part 2 (Marvel vs Capcom)
As the battle continues on, Sigma and Ultron began their all-out on each other with their vast arsenals of weapons, skills, and vast intellect on numerous strategy and experiences in their recent battles with their enemies in the past. Exchanging blows one after another to another in hand-to-hand combat, withstanding the pressure, the endurance, inflicting corruptions within each other, re-writing their codes, etc. When Sigma got the upper hand on transferring his consciousness to his colossal form to end Ultron, like a puny ant. Ultron was able to fast enough to also transferring his conscious into his colossal form known as "Ultron-7", thus begin their major colossal assault on each other and then clashing each other with their laser cannon: causing a huge explosion and so goes on the fight.
