Damian Darklord, or sometimes simply Darklord, was a re-occurring villain in Erik Larsen's The Savage Dragon comic book series who would have major ramifications on the series every time he appeared.
The sub-plot that would eventually become Damian Darklord's story started in the Savage Dragon's half issue, a special issues available through Wizard magazine when the Dragons' son Malcolm was kidnapped by the Covenant of the Sword. Though the story of the Nega Bomb and its effects date back to the earliest Savage Dragon issues as part of the original of the vigilante Mace.
Larsen based the character on Thanos of Marvel Comics.
