Episode 12
After her pokemon failed her at the last moment, and with Red's very own "Beat The Clock challenge" ticking, she needs to become experienced soon, and what better way to become a big name than get a gym badge? Her challenge is Kane, the legendary wrestler and pokemon trainer who became mayor of Knox County, and holds the position as the leader of Coolsville's Fire Gym to this day.

Waiting backstage Red finds the legendary Coolsville Gym Leader Kane, but he introduces himself as having lost the legendary part long ago, and when Red mentions her name, he nervously tells her to go find another challenge since his pokemon can't fight right now. When asking for other gyms, Kane mentions the Water Gym in a nearby city, but it's leader is a very dangerous man and recommends her to stay away.

However, from nowhere emerges the very Water Gym Leader, that's gotta be... that's gotta be... Blue Kane. Kane tells Red to stand back and deals with Blue Kane himself, even despite the type disadvantage...

Unable to defeat him with his ineffective attacks, Kane manages to paralyze him. Kane turns to Red and tells her, "La Carderina", that he knows her name because he's the very one that gave it to her as a little goblin in tribute to her uncle. Red, daughter of The Big Red Machine, is surprised to recognize her dad not having seen him in years since he left in his quest for children's pets. Kane is decided to stop the madman Blue Kane, and tells Red to carry his legacy, and before the palsy on Blue Kane runs out, he calls Red a true champion.

The Dark Web Rumble
Some people rumor that he survived the ordeal of his own self-sacrifice, and reclaimed Regigigas, making a vow to never appear on-camera ever again to not have to meet Red, protecting her from facing danger, as is his duty as a Pokémon master.
