The Top 20 Greatest Battles Of All Time

The YouTube channel Watch Mojo have done one here of what they think is the top 20 best battles from the anime.

I would have put the Ash vs Paul at The Sinnoh League as number 1 which was epic if I'd have done it rather than 6. Won't mention which match though. You'll have to see for yourself.

Personally I'd put Ash vs Kukui (League) as my top battle. Beautiful animation and the entire battle was just so powerful. Glad to see he has it on his list too!

The setting of the Alola league rather ruined the Kukui battle for me, sadly. While I could appreciate the aesthetics, it left me feeling nothing because of what preceded it.
Ash versus Paul was undoubtedly the best for me. Other than the obvious ones - Ash versus Gary, Dawn versus Zoey, Ash versus Alain - a few less 'impactful' ones I really enjoyed were Ash versus Olympia (specifically Pikachu's role), Ash versus Conway and the short but sweet Cynthia versus Flint.
The only one in that video I truly disliked was Ash versus Gladion. I could say many unpleasant things about it, but do not want to sour what should be a positive thread. Instead, I will mention Ash versus Lisa from the start of Spell of the Unown - that is one of the ones I go back to watch the most.
