I Actually picked these guys up myself, as the box-art looked way rad.
I'm still trying to track down who exactly they're KOs of, but they look very Takara Braves. (haven't watched the video yet, my google-fu brought me here, so sorry if you mentioned).
I think they're ace little guys, but the sniper rifle weapon is utter pants, but the general design work is good for the individual bots. The firestorm shares a lot of transformation beats with universe inferno. Combined mode was a bit disappointing. I feel it would work a lot better if it wasn't made out of that ghastly disposable plastic fork material.
Most fun I've had out of them so far is planning on repainting the police car one into one of the G1 light-bar Lambos, clampdown, deep cover or red alert. Not decided just yet.
