THIS IS THE JAPANESE VERSION OF MASTERPIECE ACID STORM.
One of the lesser known Masterpiece release by TakaraTomy in Japan is MP-11A Destron Warrior Acid Storm release in 2013.
Everyone knows about the Toys R Us release in the USA, but there was a concurrent one in Japan that repurposed the purple and black band packaging of its USA counterpart.
The big difference is the strip of information at the bottom calling it out as MP-11A instead of the stupid MP-01 designation by Hasbro in the USA.
The toy remains unchanged, but perhaps the points are a little sharper than the USA release. We cannot confirm it at this time!
Comes mint in sealed box.
