I look forward to the next chapter.

nice.

nice

Oh shit! Going after that Shiny Metagross. Count me in!

Hmm. Interesting take on an older Ash.

Amazing.

Nice.

Soo Ash was drinking how old is he or was he on a titty bar?
Never liked Dawn much prefer Zoey more but she is the girl of the region and Ashy gotta leave a kid on every region so they can keep his Ketchum lineage alive.

wow chimchar is tough

yeah dawn should get charmander!

Monferno already? didn't he only evolve after Ash had like 7 badges in canon?

I really like competent Ash.

It was cool to read another chapter from you! It's been a while, and overall it was a fun read.

You're not aspiring to become a published novelist ( ... right?), so I'm going to leave a more casual review than I would with Elf or some others. Couple small notes of con-crit to start with though:

“Ash looked up at the large towering brick building he found himself standing in front of, dome like in shape with a gleaming orange yellow roof …” I'll keep this short, but don't worry about writing description for the sake of having description - at that point I'd actually argue it's better to skip it entirely. Good description isn't about what Ash literally sees, but the impression it leaves upon him and/or the reader. That's why cliches like lightning forking through the sky while the MC approaches a darkened house exist ... it's meant to leave us with an impression and opinion about the place. But of course I'm not suggesting you do cliches like the example I just mentioned - plenty of other ways to leave a visual impression.

Lots of people don't seem to get this, which is probably why I enjoy writing description whereas most people hate it. If you use it right, it can be a shortcut instead of bland padding. I know you're describing how the gym looks in canon, and it's not a bad description at all, but I would've loved to get into Ash's head in that moment and seen how his impressions colored the description of the gym, if that makes any sense.

The only other con-crit I've got is to be careful about triple negatives, and that I'm not sure how I feel about pseudo-legendary as an in-universe term, since it derives from base stat totals. The comment about triple negatives comes from this line lol:
“… I wouldn’t have sent him out if I didn’t think he couldn’t take down ...”

I spent a good minute parsing that, but eventually came to the conclusion that the triple negative combined with the subjunctive case ("if" case) means that this line means the opposite of what you intended. Easy trap to fall into though, we've all done it.

Anyway, I like that you're introducing later Gen moves in this story. That should introduce some additional variety and fun. And maybe this was just meant as an offhand mention, but Bayleef/Meganium taking on a more important role as the team medic (that can still kick ass in her own right) would be really cool to see. It's so logical that I don't know why no one's ever mentioned that idea before - I've seen more fics that have canon Ash get a Chansey or Gardevoir than those that take full advantage of the pokemon he already has.

I also have to say that you write canon Ash incredibly well. Most people that try to write canon Ash - instead of an AU Ash like in Traveler - magnify his worst traits and make him annoying to read about. But in this story feels very true to the spirit of canon Ash's character, and I can easily imagine him having become like this in the anime if he wasn't put on formulaic railroad tracks. Kudos for capturing Ash's voice so well. It's probably the highlight of this story so far.

Last thing, though I think we already talked about this years ago lol. I'm glad you've set in place the conditions for Piplup to evolve. In retrospect I would have liked Dawn much better if she’d had an Empoleon by the end of the series.

Looks great hope to see more of this story. I was worried you abandoned it.

Could you add another chapter to your world Sinnoh with skill fanfic?
