Koga: So you remember everything you say? How about this, Tentacruel, go!
Una: Tentacruel?
The jellyfish Pokemon shoots massive blast of water at her but she dodges them using her new wings and tries to go in for a Twin Needle. She's grabbed by it's tentacle and slammed around.
Koga: Even after evolving, you're still weaker than expected. I guess relying on a bunch of bugs wasn't worth it. I should've trained some Oddish or Bellsprout.
Una: Taking even more childhoods? For your selfish vision of Kanto?
She slices her way out of the Tentacruel's hold and blast it with a barrage of Pin Missiles.
Una: I'm not scared of you anymore. And I'll never let you put anyone else through what I had to go through!
The Pokemon restarts its assault withs its tentacles but Una cuts her way through and stabs it with another Twin Needle.
Koga: Tentacruel, Water Gun: 80 Shot Blast!
The Tentacruel reveals the rest of it's tentacles and shoots Water Guns from each one of them at Una, leaving her on the ground.
Koga: Looks like your luck has finally ran out. I finally got to see your true potential and I'm still dissapointed. You say you remember all of my tricks yet you forgot all the jutsus I taught my Pokemon? Sad.
At that moment, Koga's Tentacruel was wrapped up in silk and then dropped from the ceiling. He looks up to see Una standing on the ceiling and the "Una" on the ground disappearing.
Una: String Shot: Body Double and String Shot: Silent Drop. With only 3 moves before evolving into Beedrill, I had to get creative with my attacks. One thing I am thankful for.
Her run finally ends, knocked out by the improved version of Water Gun.
Koga: Looks like I was wrong, I really do need you to return to Viridian Forest.
Leon: You can rest for now Una. You've done enough. Now for you, how dare you call yourself a gym leader.
Koga's final Pokemon Muk is Leon's opponent. He goes straight in for a Fire Punch.
Leon: You traumatized my friend.
He keeps wailing on the Sludge Pokemon with more and more Fire Punches.
Leon: Having kids like Una kill others just because they learned about what you're doing.
He blast it with Dragon Breaths and Embers over and over and over again.
Leon: Now you threaten the lives of challengers because one of the kids you trained left to live a normal life?
With one more Dragon Rage, down goes Koga's Muk.
Leon: And you call yourself a gym leader?
Koga: ...
Rai: No response?
Koga: Here, the gym badge. I also want you to give this to Una when she wakes up, TM Toxic. You may leave now.
They exit the gym and take Una to the near by Pokemon Center, meeting up with Wart and Ivy, and leaving Una in the care of Nurse Joy.
