[Selling jars + no Gym battles + follows the main plot for the first twenty chapters, then goes its own way + no female lead + neutral protagonist + abilities from the Myriad Worlds, with Pokemon as the main focus]
Jin Yan falls into the Pokemon world and gains the Myriad Worlds Jar System. The more jars he sells, the more he gets for free.
There are also perks from the limited-time shop.
Ash transforms into a muscular Saiyan and takes part in real-life Pokemon battles. Pikachu with the Sharingan follows close behind, determined to defeat the Beast Tamer.
Brock is determined to become a professional scrap king. He used to be young, rich, and eager to pursue beautiful women, but was constantly rejected.
At the Pokemon tournament, Cynthia starts by summoning her Pokemon and turning on the stereo.
Team Rocket Trio: “Catching Pokemon can’t beat opening jars.” From then on, they open every last jar for Giovanni.
Paul is even more obsessed, turning into a crazy jar opener. Today, he absolutely has to get a 6V Pokemon with a top-tier ability and nature!
Goh wails, “I’d trade my ability to catch Pokemon with a single throw for one golden item!”
As Jin Yan’s fame spreads across the regions, every time he sets foot in a new one,
the Pokémon League goes into an uproar.
“Who cares about holding some silly Pokemon tournament? It’s Sunday, our day off. Let’s go open jars.”
The dark organizations in every region feel like the sky is falling.
“Aren’t we supposed to rely on the power of Pokemon to rebuild and control the world? Opening jars is a heretical path. We have to stop Jin Yan from selling them!”
The legendary Pokemon are even more baffled. “Isn’t that supposed to be my signature move? How come all your Pokemon can use it?”
Go go go, keep going, keep going, keep going, keep going, keep going!
I like the theme. It's better if the main character isn't morally ambiguous.
