Steamlords are a ruling caste of mechanoids inhabiting SkyTown, on planet Elysia. Steamlords were created to command the weaker Steambots. They have the ability to repair fallen Steambots with a wave of electrical energy and may even use it to damage Samus. Steamlords can also use a cloaking device to become invisible to the normal spectrum; they are vulnerable to weapon fire when visible. A Steamlord also appears in an unlockable Diorama in the game's Extras menu.
