When the mutant X-gene catalyzed in Colin Hardy, his newly gained powers of flight somehow passed on to the other members of his family.

The Knights became famous for their annual Farnborough Airshow appearance, taking passengers and performing Red Arrow style air manoeuvre displays.

During the events of M-Day, in a bright flash of light, the family lost their powers mid-flight with a full complement of passengers.

Colin's new-found hatred of Humankind over the death and depowerment of mutants all over the world, for which he assumed humans were responsible, led him to join with fellow depowered mutants and strike back by bombing the Main Line Railway Terminus in what was declared to be a "taste of what is to come."

The Scarlet Knight character has not been seen in any subsequent issues of the New Excalibur series, and with its cancellation Colin's fate may never be revealed.
