I'm not a Japanese
TF buff or anything, but from what I've read, Star Saber(and later Victory Saber) is the leader in Transformers: Victory, the Japanese only series that followed Masterforce.
Anyhow, the idea I had, is what if Star Saber was brought over to the US? What if the line never died and we got the cool Japan only
TF's that came at the end of the line? I guess the thing that intrigues me is the thought of Star Saber as Prime. I don't own the SS toy, but from pics it looks like there's a smaller jet(Prime) that hooks up with a larger vehicle(almost like a trailer, hmmmm). The smaller jet has a pilot(perhaps HiQ?), which becomes the "brain" of the smaller robot(Saber). The "trailer" part of Star Saber also transforms into a base(like a certain Autobot leader's trailer) and can form much of the larger robot's body. The smaller jet transforms and merges with the larger body to become Star Saber. It's like Powermaster Prime/Super Ginrai only a jet instead of a truck and trailer.
Maybe this is basic knowledge, but I'm just figuring it out and it sounds awesome to me.
