Dark Energon, huh? I didn't even think of that. Just saw Shattered Glass oolours. I actually like it more now that someone's likened the blade to an Energon weapon. Still probably far more likely to buy the original colours over this one though. The die-cast-y-ness of it is what puts me off. Sure it's a cool idea, but so few toys have the strength to hold something like that these days.
