The Tartarus Dragon is a gigantic and vicious being who acts as a jailer in Tartarus. He commands scorpions whose stings make his prisoners experience their worst and most painful memories.


In Keep Calm and Harry On, The Tartarus Dragon used his scorpions and taunted Harry Greenwood with his memories from his human life. Harry rebuffed his advances, saying those memories weren't real, since he lacked his own. The dragon later proved the memories were real by making him remember receiving a knife cut in the abdomen.
When Maggie Vera later entered Tartarus, the dragon used his scorpions to make her remember her mother's death and Parker Caine's betrayal. Seeing how badly she reacted to the pain, the dragon began to send more of his scorpions. Harry then taunted the dragon to make him torture him instead of Maggie, which he obliged. His torments came to an end when the demon Dante released Harry and Maggie from Tartarus.

Physical Appearance

This dragon was shown only through the cracks of prison cells. He has brown-green scales on his muzzle and a large bright green eye with a black pupil in the shape of a polygon. He also has a muffled and threatening voice. Harry called him an "overgrowth", which means it's a very large creature.


The dragon has a very sadistic nature. He likes to mock prisoners and watch them suffer from his torture.
Despite this, it seems that he is able to make concessions, as he agreed to leave Maggie alone when Harry wanted to take away her pain.
