Purity, an anti mutant group wants to get rid of Jubilee. So they frame her, claiming that she is descendant of Hitler, and is trying to start an new nazi movement. They kill few American children and few war veterans, and tell Bucky that it was Jubilee that caused it. Bucky gets one day to plan his attack. He will get ten throwing knifes. The fight happens at McDonalds restaurant. Bucky will be in bloodlust mode.
Seeing as Bucky is a professional assassin, has the drop on Jubilee, and will be fighting to kill, I'd say things look really bleak for Jubilee.... she wins 3/10 times.
so he slits a couple of guys throats while they're tired sleepy, and unprepared and all of a suddent he's the greatest thing since wheat bread? yeah he's good but he wont take jubilee so easy just one of her blasts could have the effect of a hand grenade at worst so unless he indeed does get the drop on her i say he doesnt stand a chance
Jubille was never much of a figther. Ginastic yes but nothing more. Way i see it Bucky is a much better figther. The brat was punking Grown up trained Germans ( spies and figthers ) way back in WW2. Physically speaking theres no comparation.
Of course if she hits him hes more likely down (wer her powers really that destructive? Always tough it wer more in the lines of blinding opponents ).
