Triac

Triac is a Mini-Con from the Energon portion of the Unicron Trilogy.

Triac is one of many power-enhancing Mini-Cons who help the Autobots search the galaxy for pure Energon ore.

=Toy= Triac is a redeco of the Mini-Con Thunderclash, transforming into a Cybertronic gunship. He was sold as part of the third Micron Booster assortment in Japan, in individual, blind-packed boxes so you did not know which Mini-Con you got until you opened the box and opaque black plastic bag inside.
