The Gen-14 Brainstorm?

For some reason, Hasbro seemed to want both versions of the TR Brainstorm to be limited editions, with one being in that SDCC 3-pack boxset, and the other being the Walgreens single pack version.
The bluer Japanese release (which was a general release toy in Japan) was probably made in greater numbers... than both of the Hasbro versions combined.
