Here's Yin-Yang, the combined super-robot form of Gemini and Twin. I realized that his design could be a lot better in terms of how exactly it's supposed to show how the two of them fit together to make up him, but I really wanted him to be something very different than his component parts even if that means that it doesn't look like it would really work. I tried to at least use their combined colors and individual elements in his look for a lack of any better way of showing that he is made up of the two of them. I guess you could say that the transformation into Yin-Yang is made via a lot of part-shifting and molecular rearrangement.
Yeah, as I said, the combo isn't perfect,but it is what it is and I'm glad that you get the idea. In the future, I'll have to work on showing how exactly the two of them make Yin-Yang. Perhaps another redesign, or some fancy artwork showing the changes taking place during combination or something.
