"Sure, she's young, but this "scrapyard scrapper" is as destructive as she is darling! But under that metal exterior, Mechanica is a kid like any other! Well, sort of...How many kids do you know who'd design and make a heavyweight powered suit with built-in thrusters?"

Mechanica is a playable fighter in ARMS. She was born without extendable ARMS, so she uses a powered suit to compete.


Mechanica is the only fighter who appears fully human. Her eyes lack the spiraled irises of the other human-like fighters, and she has normal human arms. She has pink eyes, and brown shoulder-length hair with an ahoge. She pilots a mech that has extendable arms made of coiled metal plates and electrical cables, and she wears a yellow and blue form-fitting bodysuit, yellow goggles, and yellow fingerless gloves.


"This youthful ARMS superfan honed her engineering genius working at the local scrapyard. She wasn't born with stretchy ARMS, so what choice did she have but to build a fighting suit herself? When she rides it into battle, she can even hover in midair! Can she soar to the top of the ARMS Grand Prix she's always loved?!"
—Official Description

Mechanica’s family has a scrapyard as their workshop. In her day-to-day life, Mechanica works alongside other employees and helps her dad with his work. When she was younger, she found a tiny TV at the local scrapyard; she used it to watch ARMS matches. There was a time when she went to watch the Grand Prix with her dad. They even managed to snap a photo with Max Brass! That experience cemented her status as a lifelong ARMS fan. Eventually, the whole workshop became covered in TVs so everyone could watch ARMS matches while they worked.

Mechanica watched Max Brass dominate the ARMS League throughout her childhood. During that time, she also taught herself much knowledge through disassembling machinery that were unknown to her. She just could not help but seek to understand the inner workings of machines. In time, her family’s scrapyard also became her work station. A huge fan of Ribbon Girl, Mechanica decorates her workshop with numerous stickers and drawings of the pop star. Mechanica enjoys watching her compete in ARMS the most! As a superfan of ARMS, she also aspires to compete in the Grand Prix herself. She created plans for her fighting suit with extendable arms at the scrapyard. The suit was the only way for her to contend with other ARMS fighters, as she was born without ARMS abilities.

With the skills and knowledge she gained from tinkering with machines, she built her fighting suit at her workshop using old spare parts and other junk she collected there. It is assumed that she had not just experience, but also talent, as she built something so complex at such a young age. Though Biff later questions the legality of her suit in the Grand Prix, it is a fact that she is allowed to enter. She entered the tournament at the age of 15. She is something of a local celebrity in her home scrapyard due to her accomplishments up till now.

Her hefty suit puts her at a weight of 545 kg, but she has a decent amount of mobility through the inclusion of thrusters on her suit. Her jetpack allows her to hover and dash in midair, even as a heavyweight fighter. However, her suit isn’t the only thing of hers to accompany her into the ARMS Grand Prix—her home scrapyard is also included. Her workshop was remodeled into the stadium known as the Scrapyard for the tournament. Her dad and his employees awaits Mechanica’s debut at her home stage—which was actually built to her specifications! It is a dream of her dad’s for her to return home with the championship belt.


Mechanica is a heavyweight similar to Master Mummy, meaning she can armor through attacks that would put other fighters in hitstun. However, she is designed to be somewhat more agile, having the ability to hover in midair while attacking and the option to extend her dashes by holding the dash button.
