To infiltrate the Seed itself, Samus guided several Galactic Federation Demolition Troopers to the Transit Station Leviathan on the Skyway, where the Pirates were mining the Seed's Phazon directly from the Leviathan. The Demolition Troopers destroyed the entrance to the Seed, and Samus traveled inside via her Gunship where she faced Omega Ridley, the guardian of the Phazon Core.
