Passenger AU: After finding out that Hiro's the San Fransokyo Killer, Tadashi starts making him battle bots. They're not very good quality, and they don't have remotes. They're meant for a technopath after all. Next news article about the Killer mentions that he was surprised by two Passengered people while already fighting one, but managed to win anyway due to his robotic allies. It got caught on a security camera, and he used his abilities to make it blur out his face.
I bet Tadashi got the idea while he was pacing their room one night while Hiro was out hunting, freaking out and thinking up all sorts of dangerous situations Hiro might be getting himself into. Eventually his eyes fall on Megabot sitting on Hiro’s desk, smiling at him with the angry face, and he gets a brain wave. Immediately he starts digging through Hiro’s stuff, looking for every single note, blueprint, and sketch Hiro might have of battle bots.
His first few attempts are kind of duds, because he’s trying to figure out how to make them strong enough to fight a Passenger Host while also being fast and quiet enough to keep up with Hiro without drawing attention to him. It doesn’t help that Tadashi’s idea of a robot is usually a lot more harmless and cute. But he keeps at it, night after night, until he has a functioning prototype.
Hiro’s Passenger is not a fan of the robots. It considers them insulting, as if Tadashi is implying it can’t keep Hiro safe on its own. But the first time they get ambushed and Tadashi’s bots save not only Hiro but the Passenger, it grudgingly accepts that they have their own merit.
Of course, the first prototypes get trashed, so Tadashi has to make new ones. But he learns from his mistakes, and every version of Hiro’s guardbots after are stronger, sleeker, and more powerful. He discovers he has a bit of a gift for creating murderbots when he puts his mind to it.
The Dark Passengers suddenly have someone new to fear.
