RMS-099 Rick Dias - S1.E12

Quattro Bajeena boards his Rick Dias for a battle simulation to transfer combat data to the mass-production model. The data personnel has some fun with him, turning the Rick Dias's monitor red, revealing his own old Zaku from his "Red Comet" days as his opponent. Quattro is gradually cornered by the Zaku... Can he win against the legendary Red Comet?

And then he switches to the Hyaku Shiki, and faces off with an old rival...
