Background: At the age of thirteen, Willie left his hometown of Aspertia to pursue new challenges. After spying on them training one day in Flocessy Town, he was c chosen by the legendary Swords of Justice to look after Keldeo, their newest member. Willie continued his adventure in Unova, eventually becoming strong enough to defeat the champion. Afterward, he left Keldeo to train at Pledge Grove. Willie then continued on, catching all of the Pokemon in the Unovian Pokedex, and gained access to the faraway Nature Preserve. There he met his soon-to-be-friend, Alduin, his shiny Haxorus. Alduin eventually became one of the most reliable allies on his team. Willie then went back to Pledge Grove, and there, standing proud in his new Resolute Forme, was Keldeo. Happily returning to the team, Keldeo had grown strong, and soon became Willie's most powerful Pokemon. After some time, and meeting the infamous trainer N and getting the legendary Pokemon Reshiram, Willie set his sights on the newly built Join Avenue. The avenue got so successful, that Willie changed the name to Red Avenue, after his idol growing up. A year afterward. Willie returned home, dropping off his Pokemon at Professor Juniper's lab.

Hello again! Kamai tagging back in!

So...looks like you're still pretty much following the story of White 2. Hugh, who isn't the Hugh from the story, is evidently still that same Hugh, because he still has to rescue his sister's Liepard from Team plasma. Much of the biography is still the story of White 2, just with explanations as to why it isn't.

Again, this still doesn't explain why the Swords of Justice would choose Willie to train Keldeo. He just happens to stumble upon them, and they're like: "well, guess this kid can help."

Does Willie possess some remarkable qualities? Is he an upholder of justice, or is he a surprisingly strong trainer? I can't imagine they saw him as a strong trainer, because he hadn't yet received a Pokemon to start his journey. So they tested him, and he was just an Ace right off the bat? This is what we mean by "Marty-Stu" characters. Willie is just too good at what he does to the point where he doesn't seem real.

Holly hatched from an egg after he met Keldeo?

Now, I can tell the editing wasn't particularly thought out, because you mention that Willie steps down as the Champion, despite the fact that you never mention him becoming Champion.

Also, nitpicky, but please be sure to organize the biography and personality sections. There are a bit about personality that I'd prefer to see in the Personality section.

I'm sorry if we seem super nitpicky, but we since there's a lot of PvP, it gets messy if everyone was already a champion or already some fantastic trainer.

My recommendation is to start from scratch and try to come up with a new backstory for the character. I know it's a bit time consuming, but I promise that it's worth it.
