Here's what my Luce will be in my (eventually) upcoming Brit-Flash comic.

The newest member of the Meta-being criminal gang: The Mercury Mustelids. Following The Event, Lucy Thawne, developed a serum for accelerated healing for the Military and frontline medicine. Unfortunately, her serum was only effective on a few races and came with huge side effects. It attracted the attention of the Mercury Mustelids founder and leader, The Mastermind, as it proved effective of his team. She joined with the promise of extra resources to refine and perfect the formula. She tested it on herself and after the initial fever and violent spasms, she gained temporary super-speed.
