But basically, We've been used to seeing robots that are simply machines from other sci-fi and science fantasy, space opera genres. The robots in these lores are simply machines created and given life to by humans, nothing more than a complex set of algorithms & programming that make them act and move about like humans. There are stories where machines started to think, finally rose up and rebelled against humans and taking over Earth. Essentially, though, they're still machines. With Transformers, we know they're living organisms but are different from what we've seen in all of sci-fi, science fantasy, space operas. We've seen all sorts of alien life forms from the aliens in the Alien franchise, Close Encounters of the Third Kind, Star Wars, Star Trek, to E.T., to The Abyss, to Men in Black, etc. So it makes you ask: why are there no Transformers-like Jedi or Sith or Transformers-like bounty hunters in Star Wars, even in the newer Star Wars prequels where CGI would make such characters like this possible; why are there no Transformers-like characters in Star Trek where since it first aired as a TV show, they've already shown so many types and species of alien life forms, even including silicon-based life forms. Which is funny to me because as I think about it, not one of these franchises, though ground-breaking as they were for the concepts of extra-terrestrial life they've introduced, I don't think they've ever thought of & used a concept such as giant living bio-mechanical shape-shifting aliens. From the old Twilight Zone TV shows to the old (and even the new) Star Trek TV shows until today's sci-fi movies, most still use the most commonly used trope for E.T. life - carbon-based organisms or a variation thereof, as opposed to Transformers being made out of sparks/energon, being energon-based or spark-based living organisms that are made of living metal, electronics and computers. Which is also funny if you realized that, since Transformers introduction in 1984, not many writers/ authors/ TV show & movie creators (or probably not ever.. I couldn't think of anything else that is remotely similar - aside from Gobots which is now owned by Hasbro - to Transformers in the 80s to 90s throughout the early part of the 21st century until 2007) have tried to cash in on the concept.. with Aliens, we've had several movies that took ideas from it from movies like Xtro to Pandorum, to its variations like Species, Splice, etc. You have War of the Worlds to movies that took ideas from it like Independence Day, Battle LA, etc. You have Invasion of the Body Snatchers that led to writers coming up with The Thing and next year's Life. which i think i probably know why: if they did try to at least cash in on Transformers-like forms of life, they could've probably gotten away with that in the 80s or 90s. today, though, it would probably be harder to introduce living, sentient/sapient, shape-shifting robots without automatically thinking of Transformers. even when Terminator Salvation came out, it was already subject to degrees of comparison, of how the machines (at least the Harvester) started becoming similar to Transformers and giving it names like "Transforminators" (even though Terminator was the most effective story told of a killer robot from the future and was the first effective live-action portrayal of a robot, despite the dopey stop-motion effects from the original Terminator, which years later is followed by Short Circuit, etc.) It's just something that I always think about because in that sense, the introduction of Transformers in 1984 until now is original. It has gone through many re-inventions over the years, butI love where the Transformers stand at this point.
