Dark Marbles is a male Earth pony residing in Opprestria with his brothers and one of the main antagonists from My Little Pony: Cutie Mark Magic Team. It's not known who his Equestrian counterpart is.
Though he is Star Speed's servant, he is the exact opposite of her. He is rather shy and soft-spoken, only ever willing to say "Oui" and/or "Non" (which is 'yes' and 'no' in French, respectively). He often lets his brothers speak for him and lash out at Heart Strike and her sisters when he couldn't.
- He mainly serves as Star Speed's servant.
