I was thinking of making a custom movie version of Ultra Magnus, but I dont want to have twin figures with differnt paint jobs. So I was thinking "Just get a Classics Ultra Magnus!" But I dont know how they look in scale. I was hoping they would be close, seeing as how they are both Voyagers, but we all know how off those can be. So can anyone post pics of Classics Ult. Mag and Movie Voy. Prime together in both forms?
