Dominic Atlas Hyde is one of the Seven Guns in Black Summer by Warren Ellis. Each member has undergone surgeries for gun enhancements as well additional implants. Dom's powers transform him into having a black tight suit and helmet which give him super strength and armor.

Dom is among the remaining members that feel the way to address the situation where the entire country (and most likely world) fears them after their former leader John Horus kills the President and Cabinet, is to turn themselves in. He still feels that Horus is one of them but that he's lost his mind. Though Dom disagrees with Horus' actions, Dom does not want to cross the lines yet he feels some sort of loyalty to team which includes Horus. Dom has more faith in the government than his teammate Kathryn Artemis.

Dominic's enhancement activation code word is: Herakles.
