brought to life in an hidden laboratory, the f squad was born, being able to walk through fire and breed in smoke they are the perfect assassin in war and other battles or emergencies, The Fsquad is already dead and so unable to be killed by any force. the flames on the back show the status of the F member, the more flames the more kills, the more power etc. when u need them they will come but don't scream to hard! u never know when u turn into the enemy.
