|~ Optimus Prime.|
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 A.I. are amoral and are only doing good because they were programmed to do so, they can only be Pure Good if their Moral Agency has been made clear, if they have no corrupting qualities, and if they are especially good and stand out from the other heroes (e.g. Optimus Prime and Steel).
