Clampdown came with his own hand-held electron pulse gun, this time in red.

Notes

• Due to the Lamborghini brothers evidently swapping molds during the development of The Transformers, Sunstreaker's The Transformers Universe profile described him with several features of Sideswipe's toy, including a hand-held "electron pulse gun" that the original Sunstreaker toy doesn't include. As Tigertrack was based on the pre-Transformers Diaclone toy that would have represented Sunstreaker before the mold swap, his weapon was named after the one in Sunstreaker's Universe profile.
