well they have cut through almost everything in their games so far..i think the twins do it, their strength is great and their swords are powerful, in devil trigger all this is more than quadrupled so i think if she doesnt surive her head being taken off she will lose this fight, if she can survive it then she may win, but her mini guns wouldnt be too much of a threat to the brothers
I underestimated the Sons of Sparda. Their healing factor is even greater than the Hulk's. I handicapped her too much, but then again keeping her X-buster and Tertiary Weapon systeam means instant one shot kill and that would not be fun at all. I am willing to accept her version 1 can actually be chopped to pieces, but versions 2 and onward is very, very debatable what with her enormous strength and even better durability. Needless to say her version 4 body survived(although damaged) the nullification of an entire dimension.
However they get the free slice with their Devil Trigger allowed. Without it they will have to work really hard to hit her. But since I decided to allow Devil Trigger to them after my first post I won't change my mind.
Sons of Sparda win because the Devil Trigger gives them a guaranteed window of attack she can't counter.
