You had Continued to Train Pikachu for the Upcoming Journey Because you knew that Brock was the first Major challenge and to be Honest his Pokémon have Immunities against Pikachu's STAB Attacks.

You had Green with you as she kept trying to Scam People Including a Fisherman who she tried Trading a Weedle before you dragged her off.

Y/n: Okay Pikachu Use, Thunderbolt!

Pika: PIKA-CHUUUUUUUUUUUUUU!!

She then electrocuted A Spearow as it then landed in front of Green and she freaked out!

Green: AIIIIIIIIEEEEEEEEE!! GET IT AWAY FROM ME! PLEASE! OH GOD!

Y/n: Huh? You're Scared of Spearows?

Green: No! I'm Scared of Birds! Get it away from me!

Y/n: What A Baby.

Green: S-SHUT UP!

Y/n: Okay Pikachu Try finding anything else to Beat up!

Pikachu: Pika!

He then ran into some Bushes as he kept on running around until he found A Girl Pikachu with A Flower in her hair.

Pikachu: Pika~

Y/n: Oh, Pikachu you found A Girlfriend huh? You Sly Dog!

Green: Wait, that can't be A Wild Pikachu. They don't have Wild Pikachu's with flowers in their hair.

???: Hey what are you doing with my Pikachu?

Y/n: Huh? Who are you Kid?

???: Kid? Kid!? Hey I'm 15! I'm Literally a True Teen! I'm An Adult at this Point! So don't call me A Kid! The Names Yellow by the Way. Yours?

Yellow

Green: Huh!? You're 15!?

Yellow: Yep! Oh, this is Chuchu!

Chuchu: Pika, Pika!

Pikachu: Chu~

Y/n: Aww, He's in Love!

Yellow: Yep!

Just then you all heard some Cries in the Distance and Pikachu Immediately Leapt into Action as you chased after him!

Y/n: Pikachu! Wait up! Hey!

You all soon came by A Poor Fire type Pokémon who was Laying on A Rock Injured!

Y/n: Huh!? A Charmander!?

Green: It Looks like Someone Abandoned Him. This is A Pokémon you Just don't find in The Wild.

Y/n: BASTARDS! (Thoughts) I could Probably heal him, but I probably can't because I'm afraid to show my Powers right now, in Threat of revealing them. If only I can-

Yellow: I can Heal him!

Y/n: You What?

Yellow then Puts her hands over him and healed him as he got up.

Charmander: Char! Char! Charmander!

Charmander

Charmander then walked over and began to talk to Pikachu, and they talked to for A Few Moments before Charmander walked over to you and he Just Made you pull Out a Pokeball.

Y/n: Huh? You want me to Capture you?

Charmander: (Nods) Char!

Y/n: Hm, Okay.

You then Caught him, and the Ball wiggled 3 times as then clicked!

Y/n: YES! I Caught Charmander!

Yellow: Well, It Makes sense! He's Very Happy you showed up and Grateful as well!

Y/n: Huh? How do you-?

Yellow: I can read A Pokémon's emotions as well!

Y/n: Huh, Neat.

Yellow: Oh, Can I Join you guys? I think I want to Join you Guys!

Y/n: Sure, why not.

Yellow: Yay! Thank you!

Y/n: You're Welcome. (Thoughts) Looks Like I have another companion along with Green and Charmander. Thankfully she does seem super Useful when it comes to Healing between routes.
