Topaz (トパーズ Topāzu) is a character from the anime series Sonic X and its comic series published by Archie Comics. She is a human working as an agent for the Guardian Units of the Nations and the partner to Rouge the Bat. Although at first, the regimental Topaz disapproves of the scheming Rouge and deems her untrustworthy, the two eventually become friends. Their main assignments involved striking at Dr. Eggman and retrieving the Chaos Emeralds, as well as serving as envoys between Sonic the Hedgehog and his friends and the government.
