Ash after finnishing in Alola learns from Oak of an ex-champion who'd like to battle him. Ash decided to go.

After climbing Mt Silver in the hail. He made it to Red. Ash "So you're Red. the pokemon master Oak told me about." Red "..." Ash "Alright then! Let's battle!" Red "..."

Red sends Pikachu. Ash thinks 'I can't aford any slip ups, this guy is the champion. I could send Pikachu but I should probably save my best for last. Krookodile is immune to electricity but he probably planned for that. I KNOW' "Go Sceptile" Ash sends Sceptile out. Red without a word has Pikachu use Volt tackle. Ash 'HOW DID HE DO THAT!?' "Sceptile leaf blade" It's a one hit KO.

Red sends Charizard. Ash 'Sceptile's a grass type so fire is super effective. Unless...' he mega evolves Sceptile. Charizard counters by becoming it's X mega and using wing attack "Quick attack" Both hit eachother. Sceptile is more hurt than Charizard "Pound" Charizard cuts it down with a crit slash. Ash returns Sceptile and sends his own Charizard.

"Dragon breathe" it paralyzes Red's Charizard whitch retaliates with slash "Take down" the two attacks hit at the same time making both faint.

Red sends Espeon. Ash 'It's not super obvious Krookodile is dark type. He may not realize' "Go Krookodile!" Espeon uses swift whitch does little damadge. "Crunch" one-hit KO.

Red sends Venusaur. "Dragon claw" Vensuar used sunny day. "Crunch" Venusaur shoots solar beam close range.

Ash sends Graninja. "Aerial ace" it takes fown Venusaur and Greninja becomes Ash-Greninja.

Red sends Snorlax then uses body slam but Greninja dodged and uses 5 big water shurikens. Snorlax uses amnesia and Greninja uses aeriall ace. Snorlax used rest and a couple snores befire waking up and finnishing with hyperbeam. Ash returns his fainted Greninja.

"Okay. You're stong. But Pikachu and I have been through more battles than I can count. If anyone can do it. It's him. PIKACHU! I CHOOSE YOU!" Pikachu hops down "Iron tail" Pikachu finnishes Snorlax. Red thinks back to the last time he had such a close battle and sends Blastoise.

Ash 'This is his last pokemon. I have the type advantage so...' "Pikachu get ready" Ash poses and Pikachu uses a 10,000,000 volt thunderbolt. Blastoise is down. Red "... ...!" Ash yells with a fist pump "ALRIGHT!" Pikachu hugs him. Red vanishes "Huh. Where did he go?"
