The Recovery Suit (also called Solar or Regeneration suit, colloquially referred to as the Black suit) is the black, silver accented costume that Superman first donned after emerging from the Kryptonian Regeneration Matrix. It is presumed the service robots in the Fortress of Solitude placed it on him. It is not seen by the public until Superman emerged from piloting his giant Kryptonian Warsuit. Worn in times where his power is weakened, the recovery suit grants some protection and absorbs solar energy to speed his regeneration. If he is incaptibale of flight, silver Rocket Boots are needed to fly.
