You know what's cooler then hurt your enemies? Hurt enemies AND yourself!
so, what happed is that there is a famous outlaw faction that are very VERY good at what they are doing. they even outsmart and outplay the Orokin twice! of course, Orokin do not take that good and straight up DESTROY these people down, but not all of them tho. The we know who being we know who decide to agonizingly fuse the remaining outlaws together in a mass of flesh and made the Warframe out of them. Got a weapon of war AND sending a message.
