DC's Legends Of Tomorrow: 10 Arrowverse Characters Who Should Join Season 2
9. Dr. Light
Appeared In: The Flash
Earth-2's Linda Park showed up in The Flash's second season as yet another of Zoom's minions sent to kill Barry, though she tried to kill her E-1 doppelganger and assume her life instead, only to fail, get caught by the team, and, ultimately, escape, leaving her costume behind to never be heard from again.
Presumably, Zoom never bothered to track her down and punish her, meaning she's likely still out there in hiding in E-1. As a meta, a literal outsider, and a thief with the chance at a redemption arc, there's a lot of character potential for Dr. Light joining the team in the second season to finally come back out of hiding to forge her own new identity and truly find a place for herself in E-1.
