Mugen is a redeco of the Armada Air Military Mini-Con Team Mini-Con Terradive, transforming into a "Blackbird" style stealth jet. He ... has a third three-bladed-claw mode. A 5mm peg was added to each of his heels so that Mugen could be used as a hand-held weapon by most larger Unicron Trilogy toys as well as be mounted on a Powerlinx plug. (Ironically, the Cybertron incarnation of Wing Saber is unable to hold 5mm-peg accessores in his hands.)
