I am surprised that there is both Incineroar and Lycanroc in the list because there can only be one true ace, at least I think so, I will skip Pikachu because it is known that it is Ash's first starter
People often choose such aces with which they started a given Pokemon series, of course, not everyone, however, nostalgia and first impression alone can do their thing, there is nothing wrong with that, it's the same with me and I'm going to present my picks
1 Charizard - I started this series with him, a strong ace faithful pokemon was constantly training for it, deserves more attention, it's a pity then he was forgotten by Ash, everyone remembers how he lost the league and then rehabilitated himself
2 Lycanroc - Kuki's Pokemon that won the pokemon league but lost to Thanos with a snap in Swoprds and Shields. Seriously though, I liked how he fought and didn't give up that was something, only why he's higher than Incineroar is the Alola league win
3. Incineroar - like the colleague above, he had a rival and fought with him, it's a pity that we weren't shown more of his skills, of course, after evolution and in a given series, not in the current one
4 Sceptile Like Charizard defeated the legendary pokemon, he is very strong and has strong moves, it's a shame that after Sinnoh we didn't see what he can do
5. Infernape - As I like fiery starters, this one had a similar story to Charmander and Tepig. He is strong and very powerful, but he lacked something like Charizard or Scepitl, but that does not mean that I consider him weak
6. Lucario - After the 8th Pokemon movie, who wanted this Pokemon for Ash's pokemon ? Infernape and Greninija then kicked him out of the squad because it was necessary to promote a given generation. He is a perfect match for Ash and Riolu's character was like the Ash of the first generation
7. Greninja - Similar to Sceptile, but with the trait of Ash's woods, which means they don't like to lose. Honestly, his design repels me because the wrapped tongue looks a bit ugly but the appearance doesn't matter and what kind of Pokemon it is. And it is shown here that Kalos was the only one of the entire team to do something. too bad Ash let him go
8. Krookodile - It's hard to call him an ace, he's strong but that's it, although since he was Sandlie I wanted him to go to Ash
