TheSteel Diver (スティールダイバー,Steel Diver) is a shooting item resembling a submarine that appears inSuper Smash Bros. 4 andSuper Smash Bros. Ultimate.

The Blue Shark as it originally appeared in
Steel Diver.
This item originates from theNintendo 3DS titleSteel Diver where players pilot submarines and fire torpedoes at enemies. When the torpedoes were fired, their speed started off slow but would speed up afterwards. InSuper Smash Bros. 4, the particular submarine that is used in the design of the gun is the Blue Shark, and the torpedoes it launches inSSB4 behave the same as inSteel Diver.
Overview[edit]

The Steel Diver in
Smash 4.
When used, the Steel Diver will launch torpedoes that move extremely slowly for a moment before accelerating to high speed. The torpedoes inflict decent knockback that can KO around 160%. Only two torpedoes can exist at once; they can travel slightly less than the length ofFinal Destination before exploding on their own. The Steel Diver holds ten shots. It is also available as an item inSmash Tour, and can be activated to hold one from the start of a battle.

This weapon is modeled after the ND-03 Blue Shark, a balanced submarine that appears in Steel Diver. It fires small, torpedo-shaped projectiles that pick up speed as they travel horizontally. Don't dismiss them based on their size—these tiny shots pack a punch!

A weapon modelled after the submarine ND-03 BlueShark from the game Steel Diver. It fires torpedo-like projectiles that start off slow, but pick up speed as they go. Those shots may be tiny, but don't underestimate them – when they finally explode, they really pack a punch!
