Droid: a droid is a robot. Not to be confused with android, which means an artificial person. Just to be clear on this point: the Vision is an android, whereas Machine-Man is a robot. Robotman, on the other hand, is a cyborg. Cyborg is also a cyborg, not to be confused with Deathlok, who is also a cyborg, but more badass. Wonder Man is not a cyborg, but an energy being shaped like a man, whereas Adam Warlock is an artificially created human, therefore an android, but he is not a warlock. Doctor Strange is, however, a warlock, but no longer a doctor, due to a crippling accident. Doctor Druid is not a doctor, but he is a druid, a member of a pagan nature religion, not to be confused with droid. As far as can be determined, there are no droid druids. Superman is a space alien, whereas Brainiac is a space alien robot. In his Fortress of Solitude, Superman often makes robot duplicates of himself, so these are robots of a space alien. Doctor Doom also makes robot duplicates of himself, which are manlike in shape, and therefore can be called andriods, but not droids. Syndrome made a battlerobot called an Omnidriod, but it was shaped like a rollerball with tentacles. There were no robots, droids, androids, or space aliens in Rollerball, but it starred James Cahn, and I think it is an underrated movie. James Cahn is not to be confused with Khan, or, as we fans like to call him KHAAAAAAAAAAAAAN.
