Mechanica (メカニッカ, Mechanica) is a character and playable fighter in the Nintendo Switch game ARMS.


One of the playable fighters in ARMS, Mechanica is a fifteen-year-old girl and a genius inventor, a talent which she developed working in her family's Scrapyard. Unlike most other fighters, Mechanica does not possess the ARMS gene causing the fighters' signature stretchy ARMS; instead, she has crafted an immense robotic suit that enables her to compete. Mechanica is a huge fan of the ARMS League and idolizes its fighters, especially Ribbon Girl. Her suit makes her the largest fighter in the game. Some of her blueprints were also stolen, implicitly by Dr. Coyle, to create Springtron. Her Grand Prix ending depicts her in a laboratory, excitedly explaining her mech to a group of scientists taking notes, with Biff being among the crowd. Mechanica's standard ARMS are the Revolver, the Homie, and the Whammer; she utilizes two Revolvers in Super Smash Bros.

In Super Smash Bros. Ultimate[edit]

Assist role[edit]
