Now that This is on the Right Thread SPOILER Is it possible that the sword that came with Powerizer Optimus Prime be a Foreshadow to the Star Saber that appeared in Legacy?
I'm not sure if its foreshadowing as much as it is "Hasbro basing a toy accesory design on an item from the show,
The Star Saber was the first Arms Micron combiner released by Takara Tomy, so I'm going to go with no. The Starsaber can be built with Bumblebee, Optimus and Ratchet's Arms Microns. I think the sword Megatron forges is will be the Dark Matter Caliber Arms Micron combiner set that came this past summer. I suppose we should expect the Cosmotector, Cosmo and Protector apparently became their own combiner, Optimus' Arms Micron shield combiner to make an appearance. It is said that this legendary shield is strong enough to ward of the attacks of Unicron and even the Starsaber
If so then pity they'd not had the forethought to make that glowy Mech Tech shit that came with the figure turn into a sword instead.
