Name any mecha/giant robot that can solo Outlaw Star-verse.

My list include:
Demonbane
Tengen Toppa Gurren Lagann
Getter Emperor
Mazinger Zero
Granzon/Neo Granzon
Cybuster
SRX/Banpreios
Dis Astranagant
Shurouga
Zelvoid
Mazinkaiser (SRW Original)
Shin Getter Robo
Getter Arc
Star GaoGaiGar/Genesic GaoGaiGar
Mazin Emperor G
King J-Der
Ideon
Gunbuster
Diebuster
Dix-Neuf
Dancouga
Godmars
Naked Jehuty
Anubis
Valzacard
Zeorymer/Great Zeorymer
Turn-A Gundam
Turn-X
Weltall/Weltall-Id
Xelguard

Mazinkaiser
Shin Getter Robo
GaoGaiGar(Star or Genesic, with the Goldion Hammer/Crusher)
Granzon
Cybuster
Getter Emperor
Dancouga
Godmars
TTGL
Valcazard
King J-Der
Gunbuster
Diebuster
and others too long to list.

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

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

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.
