She is, yes. His existence is not well-known in the 25th century.

As far as I know, that's just a coincidence. There are at least two other "human-type" Transformers with no connection to Meta Eridani III (PCHammer and Alita Ironheart; in Hammer's case, his, er, chassis isn't even based on Maximal protoform technology like Gally's is), and their transformation protocols also involve clothing or a reasonable approximation thereof. (Exactly how that works is a thing best not examined too closely.)

This could still be true, to the extent that the introduction of an alien technovirus into the environment may have altered the planet. It already had anomalous Energon before the Beast Wars, for instance, but there was no record from that era of anything like Sandstar Rho. Now, admittedly, the Predacons (except Tarantulas, who didn't exactly publish his findings) didn't care much about investigating the oddities of the world they found themselves on, and though the Axalon was a survey ship, the Maximals were a bit busy at the time, so they may all simply have missed it. If it wasn't there before then, however, that may suggest a connection. I honestly don't know—it wasn't something I consciously intended to imply in Friends Like These, anyway.
