Sulphur-Bottom

The Sulphur-Bottom (サルファーボトム号) is a massive airship which Verner Von Bluecher spent all his fortune to build and be able to enter the Forbidden Island in hope to find the Mother Lode. The airship was stuck in the island's storm after Gatz accidentally damaged the Sulphur-Bottom's engine with a attack, but the airship was able to hold until Mega Man reached the island and the storm stopped. When Mega Man obtains the 4 keys, Geetz takes over the airship by assimilating it while Sera takes the keys, but he's separated from the ship by Gatz and Mega Man must fight against him in the ship's deck.
