Hellcat
This one’s a gimme. The third season of Jessica Jones ended with Jess’ sister Trish Walker getting super-powers, becoming a vigilante, losing her way, killing a guy, going to prison, and feeling remorse. That’s a prime candidate for the Thunderbolts, and besides, we never got to see actor Rachael Taylor in a superhero costume that wasn’t purposefully goofy. Plus, in the comics, Hellcat eventually made her way to the Avengers, and the Thunderbolts would be an excellent stepping stone.
