Oak had Just Given you A Pokedex which you smiled and he explained what it was and why he gave it to you.

Oak: This is the Pokdex Y/n, and You can collect the data of Pokemon by encountering them. Encounter them all and you might be the Greatest Pokemon Trainer ever.

Y/n: Wait, where do I go though?

Oak: Try going north of Viridian Forest, over there you can probably find- HAHAHAHAHAHAHAHA!

He then walked off still laughing leaving you confused but you now had your next destination in Mind.

Later in Viridian Forest...

You were walking around the Forest Looking for A Caterpie as soon you ended up seeing some Rustling in the Bushes!

Y/n: Poli Attack!

Poli then Jumped into the fight with the Wild Pokemon but Blue's Charmander jumped in first and Began to attack Poli!

Y/n: HEY!

You Tried to attack the Charmander but Blue suddenly appeared and caught your fist!

Blue: Huh? You're the guy who tried to capture that Mystery Pokemon.

Just then A Loud Nose was heard as Blue smirked.

Blue: That was what I wanted to see.

Just then A Kangaskhan then Began to attack charging out of the Shrubbery!

Blue: Finally! Charmander attack with Ember!

His Charmander then Began to attack the Kangaskhan and he Pulled out his Pokedex to get the Data as you Pulled out yours.

Blue: Wait, how did you get one of my Granpda's Pokedex's?

Y/n: Wait, He's your Grandpa? He gave me one too!

Y/n/Blue: (Thoughts) He's my Rival!

Blue's Charmander kept on landing blows on the Kangaskhan as it kept taking damage and Blue kept on throwing Pokeballs at it but it kept on repelling them and you noticed that she wasn't attacking!

Y/n: Wait, A Second... Poli stop Charmander with water Gun!

Poli: Poli!

He then began to counter Charmander's attacks with A Stream of water and you checked inside of the Kangaskhan's pouch to see A Poisoned baby.

Y/n: Here we go, I Knew it.

You then Gave it an Antidote Curing it as it was back to being Healthy. The Kangaskhan then Began to thank you by hugging you and she then walked off with her baby.

Blue: What the hell is wrong with you!? I was going to capture it!

Y/n: I don't care! It was trying to Protect its Baby!

Blue: Fine then But I will become the Greatest Pokemon Trainer of all time.

He then walked off as you smirked.

Y/n: Really because I won't Lose to you ever again!

Blue then got angry as he walked off.

Y/n/Blue: (Thoughts) I will become the Greatest Pokemon Trainer ever!
