Best of these to take to rank 4( all are 5 stars) unawakened

Agent_X_zzz

KM, utility monger true strike, decent damage, can counter stun immune, can tank sp3s and if you mess up, nice synergies esp with void which allows him to be one of the best icarus counters in the game. After his sp3 at 50 of the bleed charges place a mega bleed dealing massive damage.
