The Heal Unit is an invention of Gerald Robotnik. Accordingly, it has the ability to restore the energy of both living creatures and robots. It is used by Shadow the Hedgehog to revive fallen GUN Soldiers or scientists in Shadow the Hedgehog. They are found in Space Gadget and The Doom. They also made an appearance in Lethal Highway.


  • According to Maria Robotnik, the Heal Unit is her grandfather's greatest invention.
  • The Heal Unit has a side effect of dizziness.[1]
  • When Shadow throws a Heal Unit at any GUN Soldier, they stand and do a saluting pose at him and will no longer attack.
  • A gun with the same power as the Heal Unit appears as an unlockable weapon.
