Bitter rivials

Shado Syndicate and Purple Vixen are bitter rivials, though the Shado are much smarter and ruthless than their purple counterparts, they pretty much had the same fate. Yet they still think they are better than them and often beat/or kill them and steal the stuff that the purple Vixen stole just for kicks. And what else to pissed Purple Vixen off than kidnapped the her best girl or new recruits and hired them as their own?
