The Power of One
There's an orphan at the centre of The Power of One (1992) who is neither a super villain nor a super hero.
Young PK has his mother for a while after his father dies, but she sends him to a boarding school. And then she dies too. Living with his grandfather, the boy is well mentored by a German pianist and a Zulu prison inmate, men who teach him how to stand up for himself because he is bullied by Afrikaan South Africans (he's English).
The film concludes with PK joining forces with Black South Africans to campaign against the rampant racial injustice.
