So... Recently, I watched one of @Rodimus Primal's videos- the one about the Matrix. This video, to be exact. The basis for his conclusions was the BW animator's use of the Matrix as Optimus Prime's spark chamber, which was inaccurate. However, I don't think that this is correct to assume that it was an error. If you watch the scene in full, Rhinox comments that- and I quote: Here's the clip. Rhinox says the line at the 0:54 mark. I think that one explanation is to use Marvel G1's Creation Matrix as a excuse: The Creation Matrix merges with one's spark, causes the spark to become volatile- so a container is necessary to keep the spark under control. This could be why Primal has to struggle with Prime's spark when he removes it. But then you have to deal with the fact that, in G1 season 3, Rodimus lost the Matrix many times but still retained his spark. Maybe the container keeps the Creation Matrix, but leaves the spark behind? That would possibly explain Prime's death in the 1986 film, actually. Without the extra boost of the Matrix, his spark gave out. I don't want to outright call a user on the boards as wrong, but I do think that this needs looking into. Any thoughts?
