Scream all you like, 'cause we're all mad here
Unicron is about a head taller (which is still not insignificant at this scale). On the other hand, Fort Max gets his height by being a stack of hollow boxes. He's tall, but very empty for the size. Unicron is much, much denser and heavier.From what I've read and seen, he's about the same height as Fort Max. Obviously parts/plastic might be more, but as they've already done the R&D, there might be wiggle room for a slightly simplified version. Who knows? Stranger things have happened.
