Tonight, our autisms merge together like the dragon ball dance.
Another possible cause is... SHOCKWAVE! we have seen bishop call these fuckers "perfect beings" and I'm pretty sure shockwave's scientific butt would have a thrill working with stuff like this.
I just searched the whole titan thing and it's a fantastic idea, I love it. The question is...how do we make the mech's find em??? I mean, Weyland Yutani has that covered but... would the events happen here on earth? On Cybertron? On Mars? On a whole ass different planet like Clemency???
perhaps... maybe a freak science experiment gone wrong from Shockwave's end... maybe Tarantulus since he dabbles a lot with organic beings more than Shockwave does.
Titians have cloaking technology so its a wonderful location for a secret lab/base because it will be undetected by outside sensors which would also make it pretty hard for our lovely Autobots & Decepticons to figure out where their queen is. I was thinking a design similiar to the Necrotitain in IDW... scary, rusted, half dead. something like that. it could be on any planet honestly but I feel like if it were on Earth then the human blood guts & gore galore would be a bit too extreme because Xenos were already hard to kill considering they overpower humans easily but now they're mechanized? With basically what is metal armour??? Oh fuck no.
I can imagine the test subject, the first one being the Queen— they underestimated the intelligence of the Cybertronized Xenomorph (Cybermorph? Mechamorph? I think I'm gonna go with Mechamorph) and it manages to break out of containment using the acid sprinklers. Problem with having a semi-dead titain is low structural integrity given its been there for millions of years unmoving.
I feel like it would start as rumours of these beings around, they don't take it seriously but then random mechs start offlining with big holes in their chassis as if something exploded from their sparkcasing and they all go "what the fuck" because its never before seen. They probably assume first that it was some kind scraplet or scraplet subspecies but then they realize its a much bigger threat the more it multiplies.
The Decepticons are dissecting these things and trying to figure out what the fuck is going on meanwhile the Autobots would probably try to attackh trackers to a few (painstaking process, a few bots nearly died) to figure out where they head next. It would work but then the moment they enter the titain, the trackers stop working and everyone is like "???".
It might happen on a more remote planet, a lot more suspense. There's only a small group of Autobots and Decepticons stationed there, thats where it starts but eventually, these things start sneaking onboard their ships and end up going to other planets and thus being this horrific pest they really need to deal with ASAP.
I feel like the plot would be really good for a Wreckers storyline, I won't lie. They're the Autobots chosen to deal with this threat. They're deployed in the spot where the Xenos were last seen and trauma ensues.
