Description
Plasma/Brave Maximus, also known as Fortress Maximus in certain continuities, functions as a colossal Autobot guardian defending Earth from evil forces. He lacks independent sentience, operating solely under the control of Cerebros, designated Plasma in Japanese media. Plasma himself relies on a tri-lateral recognition program for function rather than autonomous thought. In his separate state, Plasma responds only to Autobot energy signatures. Combined with Fortress Maximus, the unified entity reacts exclusively to human bio-energy. A critical safeguard called "harmonic resonance" detects the intentions of any attempting commander, rejecting orders driven by evil or self-serving motives. Human children prove particularly effective controllers due to their perceived innocence.
Fortress Maximus lay concealed beneath Earth's surface for eons, specifically under the future site of Metro City. Ancient human civilizations potentially aided in sealing his activation keys—the O-Parts, the Orb of Sigma, and Plasma—within structures across the globe. His existence faded to legend on Cybertron, though high-ranking Autobots and Predacons retained the truth. An Autobot team dispatched to reactivate him in the mid-20th century crashed near Castle Peak, entering stasis.
During the early 21st century, Predacon leader Megatron sought Fortress Maximus. Autobots located the giant after the Build Team encountered his hallucination-inducing defensive field. Exposure to this field reawakened Scourge's memories of his original Autobot mission, though his Decepticon programming twisted his goal towards seizing Fortress Maximus's power. Following relocation of the giant to a hidden structure in Metro City, the Autobots secured the O-Parts and Orb of Sigma. Scourge later captured Plasma and activated Fortress Maximus, but the giant ignored Scourge's commands, responding only to the human child Koji's selfless plea to stop.
Scourge subsequently amplified his human-derived bio-signature to gain partial control in the Sahara Desert. Autobots countered by rallying human children to override this command. Mistaking Koji's friend Carl for a suitable controller, Scourge kidnapped him. Carl successfully activated and piloted Fortress Maximus in a jungle, but when ordered to crush Galvatron (Megatron's upgraded form), Fortress Maximus powered down due to Carl's selfish desire to defeat the villains alone. Autobots rescued Plasma during this incident.
In the final conflict against Galvatron, Plasma resonated with the Build Team leader Wedge's selfless courage, summoning and activating Fortress Maximus. After Galvatron drained the giant's energy, Koji coordinated Earth's children to channel their energy to Fortress Maximus. Fortress Maximus redirected this energy to Omega Prime, manifesting it as the Matrix Blade, which defeated Galvatron. Fortress Maximus then transported the captured Predacons and Decepticons to Cybertron's asteroid prison colony.
Within expanded Japanese continuity, Fortress Maximus (designated Brave Maximus) returned to Earth after the prison transfer. By 2003, he formed the core of Autobot City, later receiving upgrades incorporating solitarium technology. In 2007, he hosted the Kiss Players singing group to enhance human-Transformer relations. During a performance, Sparkbots transported him and the Kiss Players across time and space to collect fragments of the "Allspark." While pursuing a golden hand holding fragments, he collided with the "Wall of Time," scattering his passengers and crashing on the planet Master four million years in the past. His technology inspired the Cybertronian leader Fortress to develop Transtectors, including Battleship Maximus.
The Kiss Players later discovered the collected fragments were actually fragments of Unicron's lifeforce. Following Unicron's resurrection and subsequent defeat by Primus, Primus created Brave Maximus to eternally guard Unicron's sealed lifeforce within Earth. Legends Universe lore further notes that Fortress discovered Brave Maximus's wreckage, including the deactivated remains of his control units, Zebres and Master.
