I think this is a good question. I have to say I've been stumped, but have thought over a couple different answers. Like finalblast said already, it would be so cool to see G1 and G2 battle it out. That would be interesting. I think if you were gonna pit Transformer vs. Transformer in some ways it could turn out to be something similar to rock, paper,scissors, so pitting Transformers of the same teams against each other would be cool.
