Miss Match is a high-ranking employee of Evil Inc. Her powers are fire-based, and she can project flames as well as use them to propel her through the air. She is secretly married to Captain Heroic, and she is the mother of Oscar and Oliver.
Oliver is Oscar's younger brother (and Captain Heroic and Miss Match's younger son). He joined the family when Cap and Miss Match traveled to a parallel universe and found a doppleganger version of Oscar who was dying due to a strange reaction to the alternate dimension itself. They decided to bring him back to their own dimension and raise him as their son. Thanks to a spell cast by the alternate-universe Desdemona, everyone in this universe accepts Oliver as Oscar's younger brother. In the alternate universe, Oliver was targeted by Justice Inc's CEO because of his potential for incredible power. It is not known whether he will be able to tap into that power in this universe.
Oscar is the son of superhero, Captain Heroic, and super villain, Miss match. He has no noticeable superpowers, but his grandparents gave him a powerful super suit for his birthday. He goes to school at the Evil Inc charter school.
