Torpedo Ted

Torpedo Teds are anthropomorphic torpedoes that are dropped by Skull Boxes underwater. Due to them being relatives of the much more common Bullet Bills, their design is based of Bullet Bills, having similar white arms and the same jet-black coloration, though their appearance is distinguished by a smug grin and a torpedo on their thruster. They first appear in Super Mario World and have made uncommon appearances since then. Due to Mario's inability to stomp on enemies underwater and due to the Bullet Bill species' resistance to fire, Torpedo Teds are usually invincible enemies and thus must be avoided.

Super Mario World
Torpedo Teds first appear in Super Mario World, and they are exclusive to one level in the game: Soda Lake. They are dropped by gloved arms protruding out of Skull Boxes, the Torpedo Ted equivalent of Bill Blasters. Torpedo Teds move in a straight line, and they are dropped in the direction of where the player is at. Torpedo Teds travel at a relatively quick speed, and they are invincible to most attacks, so players usually are required to avoid them.

Super Mario Galaxy
Torpedo Teds appear in Super Mario Galaxy after many years of absence in the main Super Mario series; they are exclusive to Buoy Base Galaxy and Drip Drop Galaxy. Torpedo Teds resemble and act like the Bullet Bills featured in this game, where they home on to players rather than travel in a straight line. However, these Torpedo Teds make a beeping noise based on how close they are to Mario, unlike Bullet Bills. Torpedo Teds are also fired from cannons that resemble underwater Bill Blasters. In this game, they can be defeated either as Rainbow Mario or by causing them to crash into an object.

New Super Mario Bros. U
Torpedo Teds reappear in New Super Mario Bros. U alongside Skull Boxes. In this game, they are similar to those in Super Mario World in both appearance and behavior. The game introduces a Torpedo Ted equivalent, where Red Skull Boxes launch a red version of Torpedo Teds known as Targeting Teds, which homes in on players in a way similar fashion to the Bullet Bill equivalent, Bull's-Eye Bill. If the player freezes one, it breaks out immediately. Torpedo Teds can be defeated in Boost Mode; in this case, when it is frozen, the player can tap on the ice block quickly and Boost Star Mode. Also, simply freezing them when another Torpedo Ted is right in front of them will defeat them (the frozen one shatters while the other continues in its path). Unlike in previous appearances, Torpedo Teds are slightly longer, their propellers are red, and the ends holding them are white.

Torpedo Ted reappear in the extension game of New Super Mario Bros. U, New Super Luigi U. They appear in the first boss battle with Bowser Jr. and in Larry's Trigger-Happy Castle.

Super Mario World television series
A Torpedo Ted, though not specifically named as such, appears in the final episode of the Super Mario World cartoon. In the episode, titled "Mama Luigi," Luigi and Yoshi, after escaping a pursuing Rip Van Fish, are attacked by a Torpedo Ted. This Torpedo Ted chases after them as they are swimming to the surface; however, the Torpedo Ted misses both of them as they are saved by two friendly Dolphins.

Super Princess Peach
Torpedo Teds reside in a few underwater areas of Vibe Island in Super Princess Peach, behaving much as they do in Super Mario World. There are also variants that are under the influence of the Vibe Scepter, transforming them into Glad Torpedo Teds.

Mario Party 10
Torpedo Teds reappear in Mario Party 10 in Blooper Blast-Off being fired out by Skull Boxes, where players need to avoid them while they are traversing to the surface. When players hit a Torpedo Ted, they spin out for one second
