Ash...I don't like...he's a 'god tier' character. Anyone who ever watched Gundam SEED and SEED Destiny could easily see the extreme similarities between Ash and Super excellent Ultra Coorindator Kira Yamato.
Let's looks at Ash, he starts off on the losing end of a few battles starting out due to inexpierence. He starts to get better and then becomes a bit arrogant of his abilites. Halfway through the first series, he matures and becomes a super trainer that can barely be touched, let alone beaten. Sure, he'll do bad for a bit, but he'll overcome the battle through sheer plot device manipulation and deus ex conditions(read as 'Pokemon evolving at seemingly convienant times.) He also intervines in a battle between two super powers(the mews) and is revealed to be the Chosen One, among other legendary titles, who is destined to bring balence to the legendary birds with the help of Lugia.
Now, lets look at Kira. He starts off rather lucky in his Strike Gundam, usually surviving slightly by luck. He gets better, then his Gundam gets destroyed. Next couple of episodes later he gets the Freedom and is only matched in abilities by four other pilots, one of which is his ally. In the first series, he's revealed to be the Ultimate Coordinator, a perfect emboydement of every favorable aspect in the human genome. Halfway through the second series, he gets upgraded to the Strike Freedom Gundam, and went through the rest of the show without being hit once.
...anyone else notice a similarity?
