Minerva

The cheerful and idealistic daughter of Mont Parta's ambassador to Japan. She attends the same international school as Shuuta and Cab. Following a plane crash in which she and her parents get injured, she meets Metalhawk and his friends at a hospital, which soon leads to her becoming a Headmaster Junior. As the oldest of the group, despite being snarky at times, she tends to act as a sort of big sister to allies like Shuta and Cab and enemies like Cancer alike.

Her Transtector takes on the form of a Porsche 959 type ambulance, and In robot mode, she wields two shock blasters - however, as her main duty is that of a medic, she rarely engages in combat.

In the Masterforce manga, her and Ginrai are titled the "Mother and Father of Cybertron", prompting her to blush.

In the Omni Productions English dub, her name is changed to Nightbeat, referencing the original American figurine on which her Japanese toy would be based. In the Legends manga, [Nightbeat](https://anilist.co/character/322552/Nightbeat) is instead a separate character from her and his G1 self, instead being a Decepticon-aligned doppelganger of Minerva from the Legends World.
