Elia Webb is a speedster who became a meta the night the particle accelerator exploded. She didn't use her powers until she witnessed the Flash, Vibe, and a speedster she hadn't seen before stopped by a man with a lightning dagger. Elia learned their true identities that night.
Cisco dubbed her Impulse and Team Flash invited her to join them.
"Are you sure you guys wanna bring me onto the Team?" Elia asked, as she stood with Barry Allen, Cisco Ramon, Ralph Dibny, Caitlin Snow, Iris West-Allen, and Nora West-Allen in the Cortex of S.T.A.R Labs. "It just seems like there may not be any more room for another hero, if that's even what I am."
Barry and Iris shook their heads at the same time, before Iris spoke, "From what we just learned about Cicada, there aren't enough heros in the multiverse. You've been a speedster as long as Barry, but you've gone way below the radar. I understand why you're hesitant, but I also know that we are going to need you," she explained.
"This guy can take away our powers," Elia replied, "I will be just as useless as anyone else in a fight with him." She got quiet for a minute, looking around the room at these faces, each one asking for her help. Finally she spoke again, "I'll stay and try to help, but I don't have a lot of practice with my speed. I would need some help," she admitted.
Barry smiled, "That's ok. I'm training Nora too, so you can join us," at the mention of his daughter, he looked at her. "What was your idea?"
Nora smiled, "Well, when you tried to fight Cicada in the future, you never consulted a Wells. So, I think that's step one."
Barry nodded, "Ok, c'mon Cisco and Iris, lets call a Wells."
They left the room and Elia was with the remaining team members, Ralph and Caitlin.
"While they're doing that, let me run your vitals and see if you need anything specific to help with your super metabolism," Caitlin began, gesturing for Elia to follow her into another room, which she assumed was a medical area.
Caitlin ran all her normal scans and performed her usual bloodwork to find that Elia was exactly like Barry, Wally, Jesse, and Nora.
"You're all good," Caitlin finally said, after the women sat in silence for the better part of the last hour, "I'll text you a diet plan with how many calories you need to consume to keep up your strength and metabolism, but other then that, everything checks out. Do you have any questions for me?"
Elia shook her head as she stood from the exam table, "I'm really good," she shrugged. "I have never really used my speed, though, for any extended period of time so I really appreciate this information and what you've done for me. I would hate to pass out while I'm trying to help any of them take down some criminal," Elia shared.
Caitlin smiled, in reply, "Don't worry about it," she shifted the subject, "Do you wanna see if the others have found us a new Harrison Wells for this Cicada?"
Elia responded with a strange facial expression, clearly confused.
Caitlin noticed and explained to Elia the multiverse and all the different versions of Harrison Wells they'd encountered over the past few years.
"Sounds like a crazy time, which I should clearly be getting used to," Elia faked a confident smile as she gestured for Caitlin to lead the way.
