IKARE!!!! HAGANE NO CYBORG!!!!!
Sorry, had to do that
On Subaru and the first episodes...
Certainly it's always seemed wierd to me that Subaru could punch her way through Gadget Drone armor. Even a bodybuilder can't do that, and even with Revolver Knuckle the drone's AMF can nullify any enhancement on Subaru's punches, especially at close range, and at speeds slower than attacks like Scwhalbe Fliegen. Kinda found it hard to swallow that Subaru was just that strong.
Subaru being a cyborg explains all of her Gadget Drone destruction scenes, since her strength comes from her IS.
Edit:
And with all her blatant mecha references from SRW to GaoGaiGar, I think the producers knew what they were doing.
