Many of us. Some of us turned from normal human-- or normal animal, in a few cases-- to something entirely alien. Some of us started gaining robotic parts, instead of powers. A few actually found themselves in possession of actual giant robot suits.

And don't get me wrong, there were never more than a couple hundred of us, at most. More than that over the course of the years the process took place, but people were often forgetting their memories and returning to normal-- or worse, we did have several deaths.
