Serpent Society bio's- http://en.wikipedia.org/wiki/Serpent_Society
Black Mamba can pretty much instantly take out all the male members of the X-men ( she showed that sort of capabilities in the recent Cable and Deadpool storyline where she pretty much instantly and simultaneously took down cable, deadpool, iron-fist, power-man and weasel) which leaves only Psylocke and Jubilee to fight the serpent society. Serpent Society wins IMO..........
