March was part of the same group trigger as Flechette, taking place three year prior in New York. March is an old nemesis of Flechette, and continues to operate in New York as a rather persistent villain.
March is a grab-bag cape, and has access to a weaker version of Flechette's power to infuse objects with an effect that would sever their attachment to most physical laws.
↑Foil is 17 and a senior. She triggered 3 years prior to her appearance, as part of a group trigger in New York. One of her old nemeses, March, was another part of that group trigger. - Private message by Wildbow, posted on Spacebattles.

“Hey, Flechette,” Kid Win called across the room, “You’ve got a bunch of powers, right?”
She turned in her seat, “Sure.”
“Anyone else get powers at the same time you did?”
“Not that I know of.”
“Could someone nearby have gotten their powers, without you knowing? Way things played out? Did any capes show up around the same time as you?”
Flechette frowned, “Yeah. A rather persistent villain.”
