Sonic the Hedgehog 3/Launch Base Zone

Dr. Robotnik's site that houses the stricken Death Egg, with spinning elevators for facilitation of travel and alarms to keep out intruders. The mini-boss uses two flailing arms. Dr. Robotnik uses three different weapons to stop Sonic and Tails: first, a static projectile launcher at the foot of the Death Egg. When that fails, Robotnik flees to the Death Egg and Sonic chases after, leaving Tails behind. After boarding, Dr. Robotnik employs a rocket armed with lasers to fight Sonic, and then finally resorts to a large pair of arms (possibly inspired by his powersuit at the end of Sonic 2) to grab Sonic in a ball and slam him into the floor (as well as the rather impressive ability to damage even Super Sonic, though taking Super Sonic to the final battle is rare).
