I really, really don't think Moon, someone who got her shit slapped by Team Skull and couldn't beat wild fucking Spearow, can win against Gladion and Null. Just impossible. The final will be either Sun against Gladion, the battle being the introduction of Sun to Gladion, or Guzma against Gladion. But considering Sun beat Kukui with ease, I doubt Guzma stands a chance. En is damaged though, so that might be a bit of a problem, but I still doubt he'd lose. He's the one who wants to win the most.
On the other hand, Gladion is even edgier. I like that. I was hoping he'd be more chuuni in a funny way, with edge mixed in, but I'm okay with max edge slowly becoming mellow too. I'm disappointed with Hau though. While I like the Malasada deal, but that being literally all he ever talks about is a step down from his game counterpart. As for Lillie, no real opinion so far. I do think she's not as good as her game counterpart. She had low confidence in herself in the games too, but her first scenes showed her running from Aether and then working for Kukui. In manga, she's been only incompetent, nothing more. While this gives more room to grow, it seems like Kusaka doesn't want to focus on her, at least not yet.
Either way, I'm looking forward to seeing where it goes. Especially looking forward to UBs. Hopefully, we'll get to see a nice match between a fully evolved, Incineroar En and Buzzwole. And looking forward to seeing Sun use Machamp ride, if he ever does.
