Fiction

Train Wars

Thunder was one of the prototype Trainbots created by Doctor Fujiyama before he would go on to create the finalized six. After three of the finalized Trainbots were activated, Nightbird managed to break out (thanks to the rogue AI, Shadow) and upgrade herself with the technology at Fujiyama's facility. Called into action, the active Trainbots met with Nightbird before she could run away with the three remaining unactivated Trainbots. The prototypes combined to form G Liner, but the combiner was taken over by Shadow's cerebro-shell program. The three remaining Trainbots did a last-ditch effort to literally crash into the combiner, breaking him free of the brainwashing. The Train Wars: The Origin

Notes

• Thunder is a repurpose of the "L Limited Express 583 Series Sleeper Train" redeco of the Diaclone mold whose original coloration would later become Seizan. His name comes from the "Thunderliner" (サンダーライナー) designation of the Diaclone No. 11 Train Robo.
