Bradley "Rad" White is a human character central to the Unicron Trilogy continuity, appearing in *Transformers: Armada*, *Transformers: Energon*, *Transformers: Cybertron*, and related comics. In *Transformers: Armada*, teenager Rad, the curious son of scientists, explores caverns beneath an observatory with friend Carlos. He touches a glowing green artifact, inadvertently activating a dormant Mini-Con starship. This signal alerts the Autobots and Decepticons to Earth, reigniting their war. Bonding with Mini-Con High Wire, Rad becomes a key Autobot ally alongside Carlos and Alexis. He uses his partner Laserbeak for reconnaissance, participates in missions to secure Mini-Cons, accesses the Mini-Con ship's computer to learn about the Transformers' conflict, aids in battles against Decepticons, and helps rescue captured Autobots and humans. During the climax on Cybertron, Rad utilizes his mental link to High Wire within Unicron's collective consciousness to free the Mini-Cons from Unicron's control. Ten years later in *Transformers: Energon*, Rad lives on Cybertron as Dr. Brian Jones's assistant. His role is less prominent, often background support. He witnesses anti-robot protests on Earth and assists during Terrorcon attacks, notably piloting the Energon Volant Accumulator (E.V.A.) to deliver energon boosts to Autobots defending Los Angeles. He later helps activate Cybertron's Energon Grid during a Decepticon assault. By the *Transformers: Cybertron* finale in 2030, Rad appears as an adult with Carlos and Alexis. He attends the launch ceremony for ancient colony ships initiating a new Space Bridge network. In comics, Dreamwave's unfinished *Energon* series depicts Rad working for AlterEnergy alongside Carlos; the series ended prematurely, leaving his storyline unresolved despite planned involvement in conflicts with Unicron and Alpha Quintesson. Fun Publications' *Transformers: Universe* comics briefly show Rad in a flashback, consulted by Rodimus Prime about post-Unicron threats from space. Rad's arc transitions from an impulsive youth whose actions spark galactic conflict to a responsible adult aiding Autobot scientific and defensive efforts, with his design evolving across the series into formal attire in his final animated appearance.
