"The sound of ripping metal is music to my audio modules."

Eternally vigilant, he prowls the perimeter of the Terrorcons' lair looking for trouble -- and hoping to find it! Then he can show off his razor-sharp teeth, piercing pronghorns, and steel-shredding claws. Unnerved by small creatures like mice, insects, and mini-droids. Has flame cannon and flame breath in creature mode, armor-piercing rocket-grenade launcher in robot mode. Combines with fellow Terrorcons to form Abominus.

  • Sinnertwin was once known as "Hell's Gaurd Dog." That is not a typo.
  • If he offers you a drink, it's in your best interest to decline.



  • The Battle Of Vernier - Scourge has a diabolical plan - to build a gigantic Ultra Mega Vernier in Florida, and use it to spin the Earth off its axis. Can the Autobots stop him?
