[CyborgGuy]

Any higher-tier super robots(like GaoGaiGar, Shin Getter, etc.) would win rather easily.

[Rock Volnutt]

Turn-A Gundam would win with its Moonlight Butterfly.
And if not, then Gunbuster would be enough.

[King Exkaiser]

Great Da Garn GX
Great Goldran
Genesic GaoGaiGar

I could write a list of made-up droids but I'm better than that! [Hides fan fiction.] Anyway, Swerve hacks OS and wins.
