Just a redeco with new weapons, the G-25 figure in the GO! line in Japan is called Black Lio Convoy... a black, white and aqua version of the Thundertron/Lio Convoy toy.
The interesting thing is that it looks to be an Autobot, or more likely, an evil infiltrator... as if no one would notice the black colouring.

Looks to be out in December for 4,200yen.
