You confused me, I see him as more black then purple, but anyway that's Giant Robo 2, brother gaint robot to Giant Robo the main mecha from the OVA anime of the same name. GR 2 appears in flash back when GR1 and his controller Disakue Kusama escapes from the evil organization Big Fire. Cervantes and GR 2 try to stop GR 1 defecting but fail. Subless link below

The 1990's Gaint Robo Day the Earth Stood Still is my favourite Anime OVA series of all time (not to be confused with the old live action series, and the 2000 boring anime series). Despite retro designs its way more clever, focused and features far better storytelling at work than most more modern looking anime. I would recommended it to anyone as a true classic of anime.
I like Getter and Mazinga too, but Gaint Robo is better. Gurren lagan just lives in all those classic series shadow in my mind.
Anyway back to Revoltech
I have the GR 2 Revoltech too, he is pretty cool for the time he was made (some years back now) i used him as a prop when I cosplayed as Cervantes.
Most of the Super robots are pretty good, the Revoltech glossy paint and exaggerated aesthetics suit them, you probably want to get UFO Grendaizer. The other super robots. The older robots are good too, not as fancy as the new ones they don't have some of the features like double jointed necks and armour parts that fold in when the toy bends the knee. i have Shin Getter and mazin Kaiser, both are good.
As mentioned above I also found the new Eva quite Nice, the old Patlabor mechs are decent to, they lack many exciting option parts but they are good for minor Labor fans like me who don't want to shell out the big bucks.
I would avoid the Blade Liger and Eva Provisonal unit 05 though.
