The first two that came to my head were Dairtan 3 for Celestia and Zambot 3 for Luna. The Sun and Moon theme of their final attacks and their forehead ascetics are the main reasons (someone in the video I put here even made a comparison before me). Now if only Celestia and Luna would do some combo attack. www.youtube.com/watch?v=vChtgB… Past this, I couldn't really think of many, at least not two that fit together like the Sun/Moon duo above. The only other Sun-Themed robot I could think of last night was Solar Aquarion, but I could think of other 3 Moon-Themed mechs: Aquarion Luna, Gx Gundam, and Dx Gundams.Anyway, what little mecha cosplay I've seen is hit and miss, but maybe these would work. It's a funny though at least. Also, Depry's possible costume: farm8.staticflickr.com/7160/68…
