マグマin ロボットガールズ

出自《熔岩大使》（マグマ大使、Ambassador Magma）。
曾经，地球遭到了外星人的进攻，这个世界里地球的创造者“亚斯”为了守护这个星球，创造了三架火箭，并赋予了她们生命。马克马就是其中之一。
作为重生的超古代机器人少女，马克马无论是内在还是外在，都是非常经典甚至有些过时的超级英雄。她的内心深处坚信正义、勇气、和平与爱是拯救这个世界的力量。相较于其他机器人少女，她会克制自己战斗时对城市的破坏。如果自己的行为伤害到他人的利益，她会在事后找到当事人道歉。“变形”是马克马最拿手的本领。与其他相较于搞笑乃至放弃了变形设定的机器人少女不同，马克马可以在瞬间变回火箭形态，靠冲击力攻击自己的敌人。
在性格上，马克马非常的偏男性。躯干部分的装甲参考了原版漫画的模样，四肢的部分则参考了OVA动画。肩部的突起是火箭副翼上的引擎，背部也有着驾驶舱的刻画。

A long time ago, the earth was attacked by aliens. In this world, the creator of the earth "wizard Earth" created three Spacerockets to protect the planet and gave them life. Magma is one of them.
As a reborn Chokudai RobotGirls, Magma is a classic and even outdated superhero, both internal and external. Deep in her heart, she firmly believed that justice, courage, peace and love are the power to save this world. Compared with other robot girls, she will restrain the destruction of the city when she fights. If her behavior hurts the interests of others, she will find the person to apologize afterwards."Transforms" is Magma's best skill. Unlike other robot girls who are funny and even give up the deformation settings, Magma can instantly transform to the spacerocket and attack its enemies with impact.
In character, Magma is very male. The armor of the torso refers to the original manga, and the limbs refer to the OVA animation. The protrusion on the shoulder is the engine on the rocket aileron, and the cockpit is also portrayed on her back.
