>Is he the most forgotten about Champion?For the most part yes.
>Why?Because he doesn't come with any special conditions; he's just a based guy that cares for his Pokémon and the people around him, and it was through his efforts and determination to pursue strength and compassion that landed him the title of champion in the first place.
Gen 5 seems to rely a lot on symbols and motifs to build its world, and I personally made the assumption that he was meant to represent the spirit of the older generations that is meant to pass the torch to younger hands, and while we see what happens when its passed to activist hands with N, we also see what happens when it is passed down to more tolerant and accepting hands like with Iris. While I do like him, I'm willing to admit that he's less of a character and more of an idea, like many of at least BW1's characters, though probably to its worst extent.
Also, as everyone else has said, he was never given a spotlight for longer than a couple minutes aside from that mediocre couple few episodes of the anime that he was in.
