Suggested by Sonic Gravityman has some powerful gravity abilities which makes up for him not being all that fast. He is strong enough to pin both Protoman and Megaman after all. That being said, he won’t be able to keep up with the fierce attacks from Sigma. Sigma has enough durability to withstand the gravity for a little while. Meanwhile his superior strength and weaponry will win him the day. Sigma wins.
Suggested by Destroyer Shadow has returned once more and he’s up against another crazy Megaman fighter. Sigma has a ton of super forms so I think this would be a fight that could go either way but ultimately he won’t be stopping Shadow. Shadow’s speed should still be enough to consistently stay one step ahead. Shadow wins.
Suggested by Destroyer Sigma is an incredibly powerful Megaman X villain. He has had many different forms over the years and an impressive skillset. That being said, he isn’t quite ready to deal with Byakuya. Byakuya is one of the strongest captains in Bleach with impressive speed and power that go completely beyond what the average fighter can hope to deal with. Sigma can fight hard but he definitely will not be ready to take down this guy 1 on 1. Byakuya wins.
Suggested by Anonymous It’s time for a battle of heavyweights. Sigma is incredibly strong in the X series and has obtained countless power ups. In a straight up battle he would destroy Giovanni in seconds. What will ultimately hold him back here is just the fact that Giovanni has so many Pokemon at his disposal. Sheer numbers can actually come in handy at times and this is one of those times. Sigma just isn’t ready to face Mewtwo, Nidoking, Moltres, Persian, and the many other Pokemon that Giovanni has. They will ultimately rip Sigma to pieces. Giovanni wins.
Suggested by Anonymous Mareep is a fun Pokemon and definitely a fairly underrated electric type. That being said, this will not be nearly enough to take down someone like Sigma. Sigma has tons of super forms that he has obtained over the years and seems to get stronger and stronger each time. At this point most of Mareep’s attacks probably wouldn’t even do all that much damage. Meanwhile Sigma can win this in a few hits. Sigma wins.
Suggested by Anonymous This is definitely a tricky fight. On one hand Deoxys is incredibly fast and has healing regeneration. He’s been shown to be a very talented fighter over the years. That being said, Sigma has had many power ups too. His speed is more about quick bursts but it will allow for good evasion. I think Sigma’s experience and raw power will prove to be the deciding factor in this match. Sigma wins.
Suggested by Anonymous Bowser is a tough villain, but he’s definitely not in the same league as someone like Sigma. Sigma has really put the maverick hunters through the ringer time and time again. He is a robot like no other with abilities far beyond what you can imagine. A single shot would probably take Bowser down for the count when you consider how much firepower this maverick has got up his sleeve. Sigma wins.
Virgo Shaka is back and now he’s up against Sigma! Sigman is known as Megaman X’s most powerful opponent and he’s definitely a threat to many fighters. He lacks the speed that Megaman X and Zero possess, but his attack power is still pretty good. Virgo Shaka is powerful, but I think that he loses this round, which means that he’s on a dangerous losing streak. Sigma wins.
