Cypher is Solid Snake's up special move in Super Smash Bros. Brawl, based on the flying security drones seen in Metal Gear Solid 2: Sons of Liberty. Snake pulls out a Cypher unit and uses it to fly upward a certain distance. The Cypher does no damage while Snake is holding onto it, though it deals weak damage to any opponent that it comes into contact with after Snake lets go and it flies off. While Snake is flying around, weak attacks will not stop him, though they still do damage to him. Unlike all other characters, Snake's up special can be reused if he is affected by a non-damaging move that would normally disrupt the move, such as a Footstool Jump. If Snake pulls out a Cypher while another one of his is still in flight, the previous one blows up.
