I added "In fiction" to the title because I'm not talking about those Marvel and Star Wars toys where vehicles transform into piloted mechas for the character or that Animorphs toy line. I'm talking about legitimate fiction where the Autobots and Decepticons have interacted with characters from another franchise. Marvel still technically counts but not Star Wars. I want this. Not this. Ghostbusters also technically counts because Ectotron isn't just a random toy only character like the other vehicle to robot character have been, he actually appears in fiction along side the Autobots and the Ghostbusters. The reason I'm asking is because when I try to look it up on TFWiki it keeps thinking I'm talking about that Crossovers toy line rather than crossovers in fiction so I'm not sure how to find a complete list of crossovers between Transformers and other franchises in fiction. The ones I know about are: GI Joe Marvel Doctor Who (Though I don't think they directly met each other Death's Head has encountered both Transformers and the 7th Doctor so I'm counting it.) Ghostbusters AND... Star Trek though I'm not sure if that's official or fan art but I recently came across this. Not only does this have Fort Max as the original Enterprise fighting along side other G1 Transformers but the original Enterprise crew as depicted in Star Trek the Animated series, also appear in this. I'm specifying the Animated series in case you didn't know because there are two crew members who do not appear in the live action series. I don't really know their names but that lion looking cat lady... and why does she look like she has a lion's mane at all when only male lions have that? And that other weird looking long necked alien dude who I think was referenced in the reboot since they can actually do that with CGI now but that dude would not have been possible in live action at the time. Also this image seems to have been mirrored for some reason because all their badges are on the wrong side. Here's another image of all the female characters together... including the weird lion lady. I can tell the art looks a lot cleaner here than it does in the image from the old TV show but that's still clearly the same characters. They even have that same weird eye look where their eye balls match their skin tone for some reason... except for the lion lady, those two animated only characters are the only ones who have actual eye color. And again this would not have been possible in live action at the time the cartoon was made. I think they could have done everything else with costume and make up but it would have been impossible to give her those cat eyes since contacts wouldn't even exist for another 20 years. And even then not everyone is willing to use contacts. I don't really like wearing glasses but I have contacts even more. Sensitive eyes, any foreign object irritates my eyes, even clean water. So I literally can't use contacts. The tail might also be a problem since for what they could do back then it would likely have been a stationary costume piece that never moves. That's likely why those characters only ever appeared in animation since it allowed them to do characters like this without any restrictions. I still don't get why all the live action characters have skin colored eyes though. They look like their eye lids are shut and they just have pupils and their upper eye lashes painted on. I wouldn't look so odd if lion lady and long neck had those same eyes but the fact that those two characters have actual eye color while everyone else have eyes painted onto skin makes it look really weird. ANYWAY... considering Transformers exists with Doctor Who and Doctor Who also did a crossover with Star Trek it wouldn't be too far of a stretch for these to co-exist as well. Anyway... are there any other crossover comics I should know about that I didn't mention?
