As the Decepticons' military operations commander, Shockwave's power is second only to Megatron, and even that is disputed. His actions are carried out with the cold, brutal clarity and perfection one would expect of a purely mechanical being—his way is not that of blood lust, like so many other Decepticons, but rather that of a scientist attempting to solve a problem. And that problem is: how can he use his abilities to most effectively eliminate the greatest number of enemies? Unfortunately for the Autobots, it is rare that Shockwave does not find an answer.

Unlike most early Transformers Shockwave was not modified into an Earthly form, and retains his Cybertron alternate mode—a 35-foot-long ray gun. He possesses the power of flight in both modes, and commands the totality of the electromagnetic spectrum allowing him to emit beams of energy in a wide variety of forms. His high energy output makes him particularly fuel inefficient, but radioactive fuel sources stored in the reactor in his chest can help Shockwave to overcome this problem. Although his logical brain centre is usually an advantage, human adversaries often pose more of a difficulty to Shockwave, as more intuitive and emotional thought processes often confound him.

While the animated series established Shockwave as fanatically loyal to Megatron, Shockwave's original bio and most fiction since have described him as coldly and patiently looking for ways to overthrow Megatron, not for personal power (as Starscream would) but simply because it was logical for him to do so. Shockwave concluded that he should rule so that no emotion should prevent the Decepticons from conquering the universe. This was retained in most comic books, where Shockwave became leader of the Decepticons.

Unusually for a 1985 (second year) toy, Shockwave was part of Transformers fiction from the first year, appearing in both the original cartoon pilot and 4-issue comic book miniseries.
