Fred's Angels AU: Fred totally can switch Callaghan's control of Tadashi to a very small robot, once he gets wind of why Tadashi's attacking them. Hiro's also has the ability to magically sense if someone's will was suppressed or not. So he immediately knows Tadashi's being controlled but he can't know who is controlling his big brother. Once they knew, with the harmless robot that Aunt Cass conjured, they were able to switch the Callaghan's control over Tadashi to the robot. 1/2
Which would prove disastrous to the team since Callaghan upgraded to harmless robot to a deadly one. 2/2 Callaghan has A LOT of nyald stones that are all working together, although some have fused into more powerful ones. The models thing does work, although Hiro is slightly terrified by HOW MUCH damage the models got during the Krei Tech fight (Callaghan has recruited SO MANY people with his stones/microbots mix). Also eventually Hiro had to turn the group's hair back to normal on his own because Fred really liked it.Fred has been known to cause some REALLY WEIRD shenanigans by humming, because a song had a metaphor for something really hard to put into words (like, say, the song Embers) and he hummed it, and used that for rule-of-symbolism. Like making people fireproof by making the fire a metaphor for a good thing. (It works, but there's a big hurry to cancel the spell before the firefighters finish putting it out, because oh no they made the fire a metaphor for life and good moods. )
Oh man, so basically magical chaos happens in this universe whenever Fred is involved. Maybe they end up taking the emerald away from him because otherwise every time he so much as sings in the shower something magical happens.
Although he’d definitely still need it when they take on Callaghan. A death robot AND magic stones? Yeeek. Y’all got your work cut out for you, that’s for sure
