Which single trainer gives the most money in each core series game?

Question

Base please, not including Amulet Coin, Happy Hour, etc.

Comments

Just because the question about black 2 was already asked doesn't mean you can't includes it. So if you are wanting a complete list it would be fine

Ok... But if you're wrong...

Not a full answer, but https://bulbapedia.bulbagarden.net/wiki/Prize_money

Yeah, I've seen that. Thanks, though.

Why do you want to know this? You can just beat the league endlessly to get money while using the "Amulet Coin and other methods".

---

Don't question his/her/its curiosity.

Apparently it depends on the trainer you're fighting and the level of the last Pokemon in your party (the latter of which I personally think is kinda dumb).

---

Isn’t it the opposing trainer’s last Pokémon, not yours?

---

that is correct, thecarnapper5

---

is it the champion? IDK

Whoops, my bad.
