He should be here soon. I don't think he can resist this topic
So without further ado...
A Xenomorph (I love that name, its too cool) is partially inorganic. If I recall correctly their cells have some sort of polymer that can form when the alien is exposed to hostile environmental conditions such as space, for example. I don't know how their DNA is composed, but I don't think its possible to have a Xenomorph
directly infect a
regular Transformer. The only Tf that would more than likely serve as a direct host would be a Predacon or Maximal.
The only way I could see a Xenomorph infect a regular Transformer would be indirectly. First an Alien would have to infect a Quintesson, as they are closest to organics, and the young Alien would have to adapt to the Quint's physiology. This Alien might become a subspecies as it adapts. The Alien may take on some of the characteristics of the Quints, including a more inorganic body. If this happens, the Alien offspring will have less adapting to do when they go into a Tf host, but they would still have to adapt. It may go on to become a new species. Probably with the ability to infect both organics and Tfs, and that would be interesting. It might even take on the characteristics of the Tf host it infects.
How about a Trans- Xenomorph for a threat?
