Alright guys I got the PERFECT theme!
Pokémon!
♪I wanna be the very best, like no one ever was....♪
It starts with a map of all the shinobi nations, then zooms in to an area of a meadow where N Tame is walking and looking all forlornly and lonely and then he looks into the camera and smiles mysteriously. Zoom out to the sky with logo, Naruto Saga, and Butterfree are flying through the sky.
♪To catch them is my real test, to train them is cause!♪
It switches to a night scene, Sousetsu and his Serperior are locked tense battle with Lamya and her Serviper. Serviper is about to attack with poison sting but then Chisaki's Shiftree jumps in using protect. Serperior jumps into the air, silhouetted by the moonlight, its tail glows as it uses leafblade to smash into Seviper
♪I will travel across the land, searching far and wide...♪
The scene changes again to a inside cave with a waterfall. The Raikage stands alone staring into the, then suddenly it freezes over. He turns to see the Ayakashi at the cave entrance with an Articuno flying above her. The three Regis step up beside Sano from inside the cave and Raikage smiles, transforming into an Umbreon, and charging ahead to shadow claw at the Legendary bird, which Aya commands to use ice beam.
♪Teach Pokemon to understand the power that's inside! Pokemon!♪
There is a scene of a ninja academy with a bunch of young Konoha Genin all taking care of their Pokemon. Tsu with a Bulbasaur, Sakumi with a Meowth, and I dunno Zinan with like a Spinarak and Asura with a Machop. (Let's pretend they're all 12-13ish). Tsu sneezes and it causes her Bulbasaur to sneeze too, causing grey power to fill the entire room and everyone panics for a few moments before falling asleep.
♪Gotta catch 'em all~ It's you and me, I know it's my destiny! Pokemon! Oh you're my best friend In a world we must defend! ♪
The dust changes into sand and the land of Wind's desert appears with two shinobi, Marley Mari and Seiryū, swordfighting it out, neck and neck. Sei commands his Larvitar to use rockslide just as Mari's Growlithe avoids it with Flamewheel to go in for the attack. Daraku and a Volcarona acting all Sensei-like cheer on Mari from the sidelines. Sei looks back at them with a face like "Really?!" but is currently busy with Mari's kicking attacks. Razan laughs beside Daraku as he watches the fight with an Eevee on his shoulder.
♪Pokemon! A heart so true, Our courage will pull us through! You teach me and I'll teach you Pokémon! (Gotta catch 'em) Gotta catch 'em Gotta catch 'em all!♪
On the mountainside, Dray/Zennyo looks out across a mountain range at the stars above as a flock of Dustox fly across the night sky. Other Kumo nin (uh Kaekio, Ryuusei, and Haruo...?) stand beside him, around them various native rock types of the rocky mountains of Kumo, a pack of Mightyena and some Durant. The camera zooms into the Senju's eyes, which morph into different man's face. The camera zooms out to reveal Uchiha Tenzō, smirking at the moon, surrounding him are some members of the rebuilt Uchiha Clan (Maybe Soichi, Susumu and Yoichi....?) all looking Uchiha scary, along with various fire types atop the Hokage monument. He holds up a stone as he activates his sharingan, a charizard flies up the cliff and mega-evolves with a flash of light. Tenzō jumps off the cliff and rides atop the Charizard into the night sky.
♪Every challenge along the way
With courage I will face...♪
At night in the desert, the camera pans and follows a Swellow through the sleeping Suna until it lands at windowsill of the Kazekage's office. Suzume crossed her arms and looks down frowning at the papers, pictures of missing nin and top secret missions. She sighs and takes her Kazekage hat from her head and places it on the desk. The swellow leaves and flies up to a rooftop to land on the shoulders of the waiting Taede, who pets it gently with a shy smile. The Swellow affectionately nudges at Taede's ear before taking off into the sky of clouds...
♪I will battle everyday
To claim my rightful place! ♪
The camera follows Swellow into the clouds, which soon clear to reveal a foggy Iwagakure. The swellow glides down to the windowsill of the Tsuchikage. Akira stands away from his desk to look at the bird Pokemon with a playful smile, his white eyes for a moment revealing their doujutsu. The door opens with a Ninetales poking its head through the crack, followed by a serious looking Nanashi who opens the door further. The Swellow flies away as the Tsuchikage turns at attention, his smile gone because now it's time to get down to business.
♪Come with me; the time is right!
There's no better team....♪
Actions shots of several gennin participating in the chuunin exams on the Genbu(Titan Size Torterra?). Especially those chuunin who run into giant Pokemon, such as giant Ursaring, a giant Dodrio and giant Hippowdon. But many fight back with their partners as well as fight each other.
♪Arm in arm, we'll win the fight! It's always been our dream!♪
Round two of Chuunin exams fights action shots. Taede uses his Swellow and Miltank against Kikisu's Shuppet and Relincanth. Maigo and Braixen vs Elin and Kirlia. Sakumi and her Meowth are beaten badly by Fukai and Mienshao. Tsu and Bulbasaur panic against Riss' water clones and her Froslass' double team. The camera zooms out from the arena focuses on Mt. Ikkyu, where many ninja have gathered at the onset of the chunin exams, form those who came for a good time of festivities to those who found new rivals or enemies. Colorful fireworks shoot into the sky.
♪Pokémon! Gotta catch 'em all~ It's you and me. I know it's my destiny! Pokémon! Oh you're my best friend, In a world we must defend! ♪
The Kages are all in their robes are are lined up on spiraling mountain elite four + champion style, looking epic with backlighting and shadows, all with their signature pokemon (besides Sano who transforms into one, his might just be Zoroark... He might just be a Zoroark).
♪Pokémon! Gotta catch 'em all! A heart so true, our courage will pull us through, You teach me and I'll teach you, Pokémon!♪

Okay disclaimer, people I don't know a lot of you and for most of these pokemon-partner matchups I just picked what was either aesthetically pleasing (yes including who got megas or legendaries) or fit what I know/have heard about you. (I've only been here for about half a year so I don't really know everyone...!) And if I didnt include you, don't worry! I still <3 you i just happened to not be able to fit you in. So it's not perfect that's for sure, however I just really, really love Pokemon and Saga and I hope you do too!
