The Super Cutter is a gimmick originating from the original Mega Man, appearing in Cut Man's stage. It is a scissor robot made from ceratanium (just like Cut Man's Rolling Cutter), thrown out at high speeds and in great numbers from a large machine.
Super Cutters were first made available in the devkit for the original Make a Good Mega Man Level, but weren't used in any entry stages. They did appear in the Wily stage Flashback Database, both in their traditional form and (in the original game) as one of Wily Machine TROPHY's attacks.
Super Cutters are spawned from Super Cutter Spawners; when Mega Man gets close to one, it will quickly throw Super Cutters in a small arc towards him. Owing to their high speed and (unlike in Mega Man) inability to damage them, and the spawners lacking a way of being stopped, the only way to deal with Super Cutters is to run past their spawners.
The exact number of steps a spawner waits before throwing another Super Cutter can be changed by altering the value of a Super Cutter Spawner's "delay" variable with creation code.
In the original Make a Good Mega Man Level and Make a Good Mega Man Level 2, Super Cutters completely ignore all of Mega Man's weapons; starting with Make a Good Mega Man Level Remastered, however, they can be damaged and destroyed as in their source game.
