"I'll call you... the flame of the spiral! Rasenhidan! That's it!"
Rasenhidan is a Gunman piloted by Lucas, and is the main robot of the fanfiction series Spin On!. Based on a disgarded Lagann, it was later upgraded from parts of other destroyed Gunman in the Kamina City junkyards. Like it's progenitor, Rasenhidan has the ability to combine with other Gunmen to agument its power. Starting at Episode 50, Rasenhidan is arguably the most powerful mecha in the series.
