Atomos (Final Fantasy XIII)

Atomos is a Pulse fal'Cie that digs underground tunnels along the Mah'habara Subterra. Its appearance is akin to a spherical boulder with a spinning circumference of glowing spikes. The fal'Cie also serves as a transport for whomever can stop it, possessing a partially hollow interior. Stopping it is no mean feat -- it requires a great force; in the case of the heroes, a number of Juggernauts team up to halt Atomos. Afterward, the player is able to ride Atomos between Mah'habara Subterra and Sulyya Springs.
