Torpedo Base

Torpedo Bases are black artillery that first appear in Super Mario World. Gloved hands from the Torpedo Base release Torpedo Teds at Mario.

Super Mario World
Torpedo Bases first appear in Super Mario World in only one level, Soda Lake, where they fire Torpedo Teds that are invincible to all available forms of attack, making the level tricky to traverse. The gloves that dispense the Torpedo Teds have four fingers.

Super Mario Galaxy
Torpedo Bases (generically referred to as torpedo tubes by Prima Games ) also appear in Super Mario Galaxy, where they sport a different design. They are most often found in the water, and now can be destroyed by leading a Torpedo Ted right back at them.

New Super Mario Bros. U / New Super Mario Bros. U Deluxe
Torpedo Bases, as well as the Torpedo Teds, return in the Wii U game, New Super Mario Bros. U. They behave and look almost exactly as they do in Super Mario World, with the gloves now having five fingers, and appear in Larry's Torpedo Castle; they are once again invincible. Targeting Teds and red Torpedo Bases debut in The Mighty Cannonship level, being both obstacles and weapons that appear in the fight with Bowser Jr. While Torpedo Teds reappear in New Super Luigi U, black Torpedo Bases do not.

Super Princess Peach
Torpedo Bases return alongside the Torpedo Teds in the game Super Princess Peach, where they are invincible.

Mario Party 10
Torpedo Bases reappear in Mario Party 10 in the minigame Blooper Blastoff, where they launch Torpedo Teds.
