The Cobra STUN is a light-weight, super-fast attack vehicle. It weighs 4.2 tons with a top road speed of 75 MPH; cross-country 44 MPH and a fully loaded range of 340 miles. It is armed with four 3.5 inch, high-explosive rocket launchers with 400 drum-fired rounds each, one 9mm circular magazine machine gun with 300 rounds.
Conceived during Serpentor's reign of Cobra, the STUN incorporates a number of surprising features into its design. The most notable is the ability of the front-mounted battle shells to rotate to the sides of the vehicle, allowing its gunners to rip into enemy forces at an angle with the rocket launchers. The driver of the STUN sits in a high rearward position, allowing him to oversee the entire field of fire, though making him an easy target at the same time.
