A character aside from the main character, irregardless of gender (don't worry, no homo), particularly in an anime that has the most influence in how the plot moves along the series.
Characters that best personify this include: Speedwagon in Jojo's Bizarre Adventure and Kongming in Paripi Koumei.

Get the Best group of 4th genmug. Giver of all things (art)
Lover of the things he gives (also art)
Giving love to his art and hoping for more love (hm. Still art?)
He loves being confused, just so as he can be right. (what?)
And then he confuses again by being so right (that's a bit cocky)
He never is cocky, only the best can allow themselves to be cocky (OK...)
Not saying dylan's the best. But the best Dylan is.
