Much like the Encore release of Unicron (Micron Shūgō-tai Color), this is a recreation of what was once a super rare Lucky Draw figure from 1999. However, also like Unicron (Micron Shūgō-tai Color), it is not a straight recreation, as this version will have less translucent plastic with two opaque arms instead of one solid and one clear.
More recently, the old Lucky Draw figure was actually repurposed in comics made for e-HOBBY's Magna Convoy exclusive as the leader of a legendary group known as the Primus Vanguard. While it remains to be seen whether this Legends release of Blue Big Convoy will fictionally represent Big Convoy himself in a new form, the Primus Vanguard leader remains another distinct possibility for this toy's character identity.
Legends LG-EX Blue Big Convoy will be released by TakaraTomy Mall in February 2019.
