The Hammerhead Shark (ハンマーヘッドシャーク?) is a type of unmanned pursuit vehicle used in Academy City.[1]


A hammerhead shark is a type of shark, named for the unusual and distinctive structure of their heads, flattened and laterally extended in a shape similar to a hammer, known as a cephalofoil.


The Hammerhead Shark looks similar to a slim sports car, being built low to minimize air resistance, with the engine in the rear and armor in the hood.[1]

The Hammerhead Shark is an unmanned vehicle which is meant to stop rampaging or dangerous drivers by safely and swiftly catch up to their target's vehicle and then crash into it to stop them.[1] With several linked via high-speed wireless internet, they can apparently force even a 20-ton truck off the road.[1]

Due to its intended purpose, the Hammerhead Shark is built low in order to reduce air resistance as much as possible and has its engine in the rear rather than in the front. Its hood is full of composite armor.[1]


Around the time of December 24th in the current year, the Hammerhead Sharks had been introduced quite recently. At the press conference revealing them, they were apparently mocked as an 'eye-for-an-eye' policy.[1]

Following her destructive kidnapping of Last Order on December 24th, several Hammerhead Sharks were sent against Maidono Hoshimi to gauge her strength before a manned unit was sent in. Maidono used her Telekinesis to create a makeshift ramp and unable to react in time, the Hammerhead Sharks ended up flying off it and crashing into a nearby third-floor window.[1]
