I just finished watching the tremendous JLU set. I think what makes that show so great is the sheer number and variety of characters they featured. They mixed together members of the Justice League, the Justice Society, the Seven Soldiers, Birds of Prey, not to mention the slew of loners. So I'm wondering why Heroes shouldn't feature characters from RID, Armada, etc. The G1 characters would be the foundation of course, just like the original 7 in the league. Wouldn't it be interesting to see Rail Racer again? Or Tidal Wave? The way I see it, as long as the characters don't contradict G1 characters(like Wheeljack and Ironhide do), there's no reason they shouldn't exist at least as background characters and army builders. I'm tired of the "small teams of autobots and decepticons are dispatched to earth for whatever reason" premise. I want to see entire armies in action.
