1. Not irrelevant since it shows he was still close to beating Brock.
2. That's semantics, the list goes on and on. You could literally use any battle from the character's Pokemon in like Ep 50 and then scale the opponent according to another battle of the opponent 60 episodes later. You get the point here, and whether or not Pikachu is or was Elite Four is completely irrelevant to the point being made.
3. Are you reading what I'm saying or just arguing for the sake of not wanting to be wrong in any point you make? I specifically stated that I don't believe Kiawe is Elite Four nor would defend it, just that the notion of using a battle from Episode 43 to justify the scaling of a clearly improved trainer by the endgame of a series is ridiculous, when there are examples of Pokémon improving immensely without even being capable of evolve in a similar manner, such as Ash's Hawlucha, whether or not they're Elite Four is irrelevant, since that's just basing your arguments off of a semantic that shouldn't matter in the point being made to a relevant extent at all.
Besides, I don't see much point in addressing Kukui here when I never mentioned his name in my argument, I was arguing about a small point from one of your arguments, whether or not Kukui is champion, elite four, or gym leader is not only impossible to know in the long run, as is irrelevant to the point I'm making here.
What exactly is even the point you're making?
1. I definitely agree that he was close to beating Brock. But that doesn't mean anything lol. The point here is that Kiawe is someone who scaled relative to someone like Brock.
2. Don't understand what you mean.
3. Again, Pokemon's strength is scaled based on Plot. Actual training experience means nothing. Ash's pokemon are always scaled based on how strong the Plot wants him to be. In the previous regions, the plot never wanted Ash to be close to Elite four tier, so even his best Pokemon were never scaled upwards to that level. However, in Journey's, Ash has been scaled exponentially and we see his Journey's team accomplish feats despite having less battle appearance compared to some of his reserves. However, the very same reserves now, will be scaled relative to Ash's current skill. Like for example, as strong as Greninja was in Kalos, it was never at a level to clown an Elite four tier Pokemon (Additionally, in its base form). We saw how effortlessly Greninja stomped current Lucario (Despite Lucario now clearly being a Regional Champion/E4 Tier Pokemon).
Claiming Ash’s Pikachu isn’t E4 is the biggest joke ever lmao when Pikachu is clearly Champion tier
Ash's Pikachu currently is definitely Regional Champion tier.
As Ash is Regional Champion tier and all of his Pokemon will be scaled accordingly. Plus, Pikachu recently also beat Wallace (Which slipped my mind previously). So yes, an actual feat further proving this.
However, Pikachu was NOT PREVIOUSLY E4 nor Regional Champion tier. As Pikachu never achieved a feat equivalent to this level. Then again, Ash's Pokemon is horribly scaled and the most inconsistent Pokemon in terms of strength.
That said, Ash was never E4 nor Regional Champion tier until Journey's (With the exception of Ash Greninja).
