“A coward who only dug holes in the underground grew up to pierce the heavens — the boy who saved the universe with spiral power.”
A skull-shaped mini-Gunmen only Simon can pilot. Capable of drilling into anything and taking control of it.
Energy born from the will to evolve. It scales with Simon's conviction — and he runs out of ceiling before it does.
The hyper-combined Gunmen running on maxed-out Spiral Power — galaxy-scale fighting force, final form.
He starts as the smallest and most frightened. Kamina's death breaks him completely — and then he rebuilds, as himself. Becoming Simon, not Kamina's little brother, is the journey the entire series traces. Spiral Power's real meaning is the strength to move forward without borrowing someone else's will.
