These are heroes who are not always in robotic forms, but are still sentient technology-based entities, like many computer programs that became too powerful. In fiction, these are usually created by humans but realize that they are more intelligent and may turn on human beings when they have the chance.

Sometimes, these computers are neutral and that they were just doing what they were programmed to do.

Since most are following their programming or were created to be good, they can only be Pure Good if their moral agency is made clear, they lack corrupting qualities and stand out on their own (e.g. Optimus Prime, Bumblebee, Rodney Copperbottom, Bigweld, Iron Giant, Clank, Mega Man, Olie Polie, Chiaki Nanami, Android 16, Jor-El and WALL-E).

By definition, they count as Genderless regardless of the form(s) they take.
