I don't remember them using Rom, but they did use the direwraiths that he fought against as villains for sure. With respect to Chuck walking, it might have just been introduced that he was able to walk on the Shi'ar ship when he was up there with Lilandra, I'm not sure if there was any explanation as to why other than he was in space on their ship. I remember him shooting hoops with Larry Bird ball hugging shorts on to go with his 70's WBA headband. I went through a few issues from that general era a couple of years ago, I had extra copies & put them into Tom's collection then wound up digging them out again after I re-read the Miller Wolverine mini.
Here's Wikipedia's explanation - I don't recall much of this at all:
"When the X-Men fight members of the extraterrestrial race known as the Brood, Xavier is captured by them, and implanted with a Brood egg, which places Xavier under the Brood's control. During this time, Xavier assembles a team of younger mutants called the New Mutants, secretly intended to be prime hosts for reproduction of the aliens. The X-Men discover this and return to free Xavier, but they are too late to prevent his body from being destroyed with a Brood Queen in its place; however, his soul remains intact. The X-Men and Starjammers subdue this monstrous creature containing Xavier's essence, but the only way to restore him is to clone a new body using tissue samples he donated to the Starjammers and transfer his consciousness into the clone body. This new body possesses functional legs, though the psychosomatic pain Xavier experienced after living so long as a paraplegic takes some time to subside. Subsequently, he even joins the X-Men in the field, but later decides not to continue this practice after realizing that his place is at the school, as the teacher of the New Mutants."
