Note: I will not make a scene or chapter for every pokemon Ash catches so if some random ones come out of nowhere now you know why. However I will keep a current list of all the pokemon Ash has caught including the ones he has on hand and ones he leaves at home if a pokemon he obtains is the same species of pokemon as he has in the canon you are safe to assume that the way he caught them are similar if only minor differences such as location or who he may use to fight and etc... since I believe some of the ways he captures some are stupid
Viridian Forest
Ash and Pikachu have been wandering down the forest trail trying to make it to the next town or city until sudden blue pokemon jumped out in front of them
"A Riolu?" questioned Ash whipping out his pokedex to get more information on the pokemon
Riolu It uses the shapes of auras, which change according to emotion, to communicate with others. The aura that emanates from its body intensifies to alert others if it is afraid or sad.
The Riolu then started to immediately started to run away after seeing other pokemon, the other pokemon started to chase it down
Riolu while running had to stop at a cliff getting in a fighting position, a bunch of spearow then started to attack it held its own for awhile but the sheer numbers started to overpower it
Ash and Pikachu then decided silently to help the riolu
"Alright Pikachu use thundershock" said Ash making a path to riolu to protect it
"Riolu?" questioned the Riolu seeing him being protected by this boy and his Pikachu
"No worries Riolu you don't have to worry me and Pikachu will protect you" said Ash then a drop of water landed on his nose signaling it was starting to rain
Riolu not wanting to look weak stepped in front of Ash next to Pikachu the two shared a nod and both got in their battle positon with pikachu on all fours with cheeks sparking and riolu with his body slightly diagonal but his head facing the spearow with both his arms down
The rain was now coming down full force, Ash remembering that water and electric type moves are stronger in the rain
"Pikachu use thundershock on all of them" said Ash
Pikachu then jumped up and launched his thundershock attack that hit all of them, Riolu noticing the damage used copycat he started glowing yellow for a second then jumped up lik pikachu and used thundershock as well making all the spearow blast away
Riolu and Pikachu were feeling very proud of themselves, Ash went into his bag and grabbed some electric type and fighting type food and told them both to eat up
Pikachu ate the food pretty easily but Riolu hesitated to eat at all
"Riolu did you get yourself in spearows territory for food, if so you don't have to worry about that you can come with us and I'll be able to take care of you and Pikachu as well" said Ash making Riolu look up in surprise
"My dream is to become a strong trainer so I can have my own gym to make money for my family and plus I love pokemon and battling, and your a strong pokemon so why not want to help my dream come true" said Ash sticking out a pokeball in front of Riolu
Riolu started to think of all the fun he can have so he agreed and tap the pokeball being ingulfed in a red light into the pokeball shaking three times then clicking in his hands to signal he caught
"Yahoo! I just caught me a Riolu!"
"Pipikachu!"
As stated up top I will not have a chapter like this for all the pokemon Ash catches but I will keep a party update at the bottom so people won't be confused too much
There are no levels in this story so don't count on Ash having a lvl 100 pikachu by the end since it won't matter like in the anime
Ash:
Pikachu
Riolu
