In her normal dragon form, Tiamat has the appearance of a pale blue Western Dragon.
In her human form, she has the appearance of a beautiful woman with straight long beautiful, pale blue hair, dark blue eyes, and a cold atmosphere that radiates from her beauty, as well as possessing an extremely powerful dragon aura within her body. She wears a navy blue skirt and her entire body is doused with the color of deep blue.
Not much is known about her personality, besides the fact that she hates Ddraig for borrowing her treasure, which was destroyed into several pieces and scattered.She also shifts the blames onto the possessor of the Boosted Gear, Issei Hyoudou, saying they need to take responsibility for her treasure or she will burn them to death. Despite her anger towards Ddraig, Tiamat was very calm towards her meeting with Ddraig. She can also be mischievous as she came up with idea since Ddraig was unable to retrieve her lost treasure, so Issei needs to take Ddraig‘s place of retrieving her lost treasure.
One of the Five Great Dragon Kings, Tiamat is one of the few legendary Dragons that are still active since ancient times. She is known to be rampaging around the world occasionally. Before the Great War, Ddraig had borrowed Tiamat's treasure for his upcoming battle with Albion. After Ddraig and Albion were killed, her treasures were stolen by human thieves and scattered around the world. Since then she has been chasing after Ddraig and his possessors for a long time, to retrieve her stolen treasure.
While Tiamat had yet to appear in the series at this time, she was mentioned in the side story "The Familiar's Requirements" by the Familiar Master as a candidate for a powerful Familiar.
She was mentioned once again when Issei and Azazel were talking about the Evil Dragons. During the conversation, Tiamat was said to be the strongest among the Five Great Dragon Kings and has blended in well with the current world and living as she likes.
Tiamat made her first official appearance in Volume 19. She appeared in the Rating Game between Diehauser Belial and Riser Phenex after the retiring system didn't work on Riser and Ravel. It was revealed that Tiamat acts as the secret judge/administrator for the Rating Games and only appears when something unexpected or malicious things happen. She does this as she is indebted to the Maou Ajuka Beelzebub and has appeared only twice in the past to resolve things for the games.
At the end of Volume 20, Tiamat accompanied Ajuka who was conversing with Shiva about Trihexa's reincarnation, she shows Shiva a blue mobile phone noticing that it was related to a Longinus.

She returns in Volume 23 along with Ouryuu Nakiri and Millarca Vordenburg at the Occult Research Club and demands that Ddraig give her back her treasure that he stole. She says it were possible, she would ask Issei to let her join his team but is unable due to her being part of the Rating Game’s management, but she will allow Ouryuu to join the team. She then leaves Ouryuu in Issei’s hands and gives a warning to Ddraig if he runs away again like he always did, she will burn him along with his possessor, Issei.
