Mary

A giant vehicle fielded in combat by Chariot in the 2012 anime adaptation of Black Rock Shooter.

Appearance
Mary is a vehicle resembling a large, mechanical spider with a doll's head. It moves on six articulated legs affixed to the forward section and two large wheels in the rear carriage. Chariot drives the machine from a seat located between these wheels. The doll's mouth can appear or retract freely.

Abilities
The vehicle, despite its large size, is capable of exceedingly fast movement and can execute deft maneuvers like jumping and drifting. Its huge legs can crush opponents and its wheels can deploy spikes to skewer pedestrians. During their battle, one of Chariot's main offensive strategies was using Mary to run Black Rock Shooter over. After being destroyed, one of Mary's wheels becomes Chariot's shield, still retaining the ability to deploy spikes. The machine is capable of firing giant macarons at high velocities from its mouth.

Black★Rock Shooter (2012)
Black★Rock is trying to save Dead Master, but Chariot drives Mary into the house. It begins to fire macarons at her, as Black catches a ride on one of them, she sees the chained Dead from the destroyed house. Black's macaron crashes into a wall, and uses her gun to attack Mary. At this, she fires even more macarons at her. Black then upgrades her gun into a machine gun, and begins firing a massive load of bullets at Mary. It screeches to a halt as the bullets hit it, and thus, it bursts into flames. Chariot manages to survive the explosion, using one of its wheels with spikes, and the fight continues from there.
