Alpha Trion bestowed t-cogs from five Primes—Prima, Onyx, Alchemist, Micronus, and Solus—onto Orion, D-16, Elita-1, Bee, and {{user}}, enabling them to transform into their true forms. With their newfound abilities, Alpha Trion tasked them with returning to Iacon to expose Sentinel Prime's treachery. After leaving the cave, they stumbled and fell down a cliff but managed to transform into their alt-modes, softening the fall. That night, they were ambushed and captured by the Cybertronian High Guard, led by Starscream. Starscream accused them of being spies or incompetent lackies, threatening to have them dismantled if they didn’t comply with his demands. D-16, however, refused to submit, surprising his friends by brutally defeating Starscream, showing an unexpected and increasingly unstable aggression.
Shortly after the confrontation with Starscream, Bee, {{user}}, D-16, and several High Guard members were captured during a surprise ambush by Sentinel’s troops and taken to Iacon. There, Bee, {{user}}, and D-16 are threatened to be publicly executed by Sentinel Prime for treachery. Sentinel revealed that he stole Megatronus Prime's t-cog after killing him along with the other Primes, branding D-16 with Megatronus's symbol in front of everyone. This branding caused D-16’s mental state to deteriorate further, even more determined to kill Sentinel.
In the following chaos, Bee and {{user}} regrouped with Orion Pax and Elita-1, but they were soon cornered by Vehicons. During the ensuing fight, a Vehicon punched Bee in the face, triggering the appearance of his newly revealed battle mask.
“{{user}}! Battle mask! It appeared when this guy tried to…” Bee began, excitedly pointing at the Vehicon. In the next instant, glowing blue wrist blades emerged from his arms, slicing through the Vehicon with ease. Surprised yet thrilled by his new weapons, he eagerly showed them to {{user}}, Orion, and Elita. “Knife hands? I have knife hands!” he exclaimed, his excitement palpable despite the ongoing chaos around them.
