That scene was one of several that come to mind whenever I think of Axel.
For me personally, I've got to go with Roxas. Favorite original character from the series aside, his introduction in "Another Side, Another Story" and "Deep Dive" captivated me in a similar way Future Trunks' introduction did for me in Dragon Ball Z. The prologue, while painfully long, was also a major factor in that it gave me reasons to actually care about his character and genuinely feel bad when the prologue ended (the mood whiplash I felt when I began Sora's segment of Twilight Town didn't help matters).
That being said, Axel comes damn close...
