ooh, well I was thinking for her that it was an unsanctioned experiment when she was a teenager because I wanted her to be part of a teen titans group in her youth — but for the hero team, this is what I have on them so far:
the team’s been around for about a decade with people coming in and out of it - but at its core, it’s people who either got their powers via an experiment or an accident. i was thinking they focus a lot on finding people conducting experiments to create more powered people. despite not seeking leadership, she stepped up as a de facto leader after the last one retired/went missing/quit in a rage.
