Ash Ketchum (Pokémon the Series: Black & White)

Ash Ketchum is the main protagonist of the Pokémon anime, and has traveled to every region so far, his loyal Pokémon by his side is Pikachu. While Ash Ketchum himself is a great and well-written character, his character became poorly-written in the Black & White seasons. He is voiced by Rica Matsumoto in the Japanese dub and Sarah Natochenny in the English dub.

Bad Qualities

 * 1) He is a very bad trainer unlike in the previous and modern generations before and after Black & White.
 * 2) His character is barely well written and instead, he comes off as pretty stupid and immature.
 * 3) He made the most stupid mistakes in said seasons, the most notorious example being the moment where he couldn't beat a newbie's inexperienced Snivy with a Pikachu, and it doesn't help that this is the series that came after the last series where Pikachu managed to tie with Latios.
 * 4) *Even if Zekrom had shut down Pikachu's electric attacks prior to Snivy's battle, he still had Iron Tail and other attacks that Ash should've used first.
 * 5) *He also brought only one Pokémon to a gym battle confident that he was going to win, unaware that he really should have 6 Pokemon on him at all times if he owns at least six Pokemon. He even left the battle after Palpitoad fainted to get more Pokemon when he should have been disqualified.
 * 6) He can also be rude towards his traveling companions at times, though this could be executed considering Iris treats him badly too by calling him a little kid.
 * 7) The problem with his team is that he arguably caught way too many Pokémon, and not many of them evolved fully, not even any of his starters. And some of them are very infamous for losing many battles, such as Unfezant and Palpitoad, the former of which lost to a Riolu.
 * 8) He just acted like he just started his Pokemon journey in Kanto, completely ignoring all his character growth from his previous Pokémon journeys.
 * 9) He doesen't go through any development to become a better trainer again, he doesen't go overcome his cokieness like he did in Advanced, nor does he try to mature and gain the trust of his other Pokemon like in the original series. They try to repeat his arc in Kanto but it failed miserably.
 * 10) His English voice is much more lackluster than usual.

Good Qualities

 * 1) He was a much better character prior to Pokémon the Series: Black & White and reverted back to his original personality starting from the XY seasons, and was much better before the Black & White seasons.
 * 2) * Speaking of which, he slightly improved in later episodes of said seasons.
 * 3) He still cares deeply about his Pokémon.
 * 4) He still thinks out of the box sometimes. For example, he won a battle against Trip by having Pikachu do an Electro Ball with an Iron Tail.
 * 5) Some of the Pokemon he owned during then were actually great, such as Leavanny, Scraggy, Snivy, arguably Oshawott, Boldore (being his first rock type), and of course Krookodile.
 * 6) He still has his funny moments, such as this scene when he says “Nothing ticks off more than stealing my food!”
 * 7) He still has his recognizable appearance and his outfit is nice to look at.
