Team Indigo's wild card is Neon Eos, the Dragonair.
Much of her strengths lie in attacking her opponent from a distance, closing in when they're vulnerable, but as you can see from some of her physical moves, she can pack quite a punch right at the word "Go!"
She may be a gentle angel outside the arena, but inside, she knows exactly how to overwhelm any rival. In addition, due to being a Dragon, she can take just as much punishment as she dishes out.
