One famous redemption arc is that of Zuko in 'Avatar: The Last Airbender'. He starts as an antagonist, hunting the Avatar to regain his honor in the eyes of his father.

Despite his initially cold and seemingly villainous behavior, it's later revealed that he was protecting Harry all along out of love for his mother. The third one could be Javert in 'Les Misérables'.

In some crossovers with other DC heroes like Superman and Wonder Woman, Batgirl has some great story arcs. For example, when they all team up to face a powerful alien threat.
