And they had the opportunity to give Ash an unique Lucario, maybe a more jolly or goofy one, but no, they preferred to give him Stoic Lucario #285, and although he has his goofy moments, we don't get to see any of them since Journeys is a mess of a series that prefers to show Pikachu for 100 episodes and THEN focus on the other important Pokemon.With the previous aces, it felt like their progressions were more natural, and they just happened to become aces. With Lucario, they’re trying to force it to be an ace instead of coming about it naturally. Like you can tell the staff not only wants it to be an ace but Ash’s best ace. The problem is that the staff just powered it up without showing us how it did.
They also keep trying to sell us on this so-called bond that Ash and Lucario have, but they haven’t shown us that. Honestly the show keeps telling us about it instead of showing us. They also didn’t give us a reason why we should root for its success. Out of all the aces, Lucario is the one I’m least interested in.
In terms of storytelling and narrative, Infernape is Ashs best aceAsh-Greninja was awfully explained
Lucario along with his other Pokemon have gone 72 episodes without having Ash lose a battle, take that as you will about the writing around that and the “creative decisions”
Krokorok and Sceptile were good for the series they were in, + points for Sceptiles performance in the league
So it goes down to Infernape and Charizard in my opinion. Especially when Infernape has been said to be honing his skills and became the best out Ash's Fire Types. Charizard also has the most feats of the anime barring Shillcario
They also just have better stories leading you to cheer for them especially Infernape
AG lost to Charizard and has horrible feats compared to Scep, Zard, and even ApePersonally, I don't think any Pokemon will ever embody the " Ultimate Ace " archetype the way AG did with Ash.
And to be honest, this is coming from someone who was previously all on board the Lucario surpassing Greninja train but now I'm pretty skeptical from the power level aspect as well given that Mega Lucario will apparently be facing non-Mega Evolved Garchomp that's taken damage from the duck.
