Death Spiral Machine

The Death Spiral Machine is a machine created by the Anti-Spirals to kill Spiral life forms by absorbing Spiral Power and converting it into ultra-dense space that resembles water. It is protected by a Spiral Conversion Field that absorbs mass and converts it into Spiral Power. A large dose of Spiral Power can open a hole in the field, leaving the machine vulnerable to attack.

During the Second Anti-Spiral War, the Super Galaxy Dai-Gurren was dragged into the sea formed by this machine and had all its Spiral Power drained before it could transform into Super Galaxy Gurren Lagann. Simon was able to supply power to the flagship's engine faster than it could be drained, allowing it to fend off the attacking Anti-Spiral fleet. The Super Galaxy Dai-Gurren proceeded to fly into the depths of the sea to destroy the Death Spiral Machine with two Super Spiral Missles, but the first missle was crushed by the pressure before it could reach its target.

Kittan Bachika entered his Space King Kittan and drove the remaining Super Spiral Missile into the Spiral Conversion Field, opening a large hole in it.
