Dr. Sunshine is the third infamous researcher known to be one of the most indestructible and invincible immortal members of the SCP Foundation, she is considered immortal but not unkillable. She can react to bullets, missiles and tank shots, SCP attacks (Including SCP-106 and SCP-035 instances) and die but come back and ‘respawn’ as she calls it when her ‘deceased’ body disappears and comes back somewhere else soon after. She can shrug of just about anything thrown her way.
