The Umbral Blaster combines the three Mini-Cons Scrap Iron, Backblast, and Blastcharge into a cannon form that can be held by most Transformers who use 5mm mounting points. The toy is a redeco of the Space Mini-Con Team, but could only be assembled with the purchase of three different Mini-Con vs. packs.
