Tartarus is a hundred meters sphere with many eyes and tentacles and after his defeat, his body was reduced to five meters. His body gives out a unbelievable aura and his presence also gives out a dark mist.
As member of the Alliance of Hell, he shared the group members concerns about for the danger posed by the Longinus wielders.
Apparently he even considered them even more dangerous than most of the Alliance members. He is also very cautious after revealing himself to DxD, he said that killing the Longinus wielders was a bad idea and planned to capture the Longinus wielders and keep them alive into the Abyss to avoid the current Longinus wielders dying and their Longinus returning to the world with new wielders.
At some point, Tartarus received a invitation by Hades to join the Alliance of Hell.

Tartarus was mentioned in Volume 24, who were arriving in the Realm of the Dead for Hades’s meeting with the Alliance of Hell.
Tartarus made his first appearance in Volume 25, where he calls to a unnamed God of Death to remind him that a human’s curse is much scarier than God’s curse and Mitsuya Kanzaki attained his Balance Breaker of his thirteenth Longinus, Telos Karma.
In True Volume 2, Tartarus participated in the meeting the meeting of Alliance of Hell with the exception of Erebus and Nyx, causing Tartarus to laugh as primordial gods like to do pranks. When Hades shows the recording of a silver humanoid, Tartarus believed that they are some misses even on the information that only the chief-gods know and it’s outside of their calculations.
In True Volume 3, Tartarus appeared after Erebus was defeated by Issei and revealed that he was watching the fight behind the scenes whether Erebus’ plan worked or not, and revealed his goal to sink his enemies into his Abyss. Seeing the Longinus users in the Dimension Lost, Tartarus determined that it was perfect opportunity to sink them in the Abyss after watching Erebus, Gressil, and Sonneillon being defeated by the Longinus users, considering them a great threat. When he was asked by Issei if he was going to kill them, he revealed that he was going to seal them in the Abyss rather than killing them as the Sacred Gear System will make new owners if the previous Sacred Gear users is killed. As Issei was calling out to Ddraig, Tartarus said that Erebus used a darkness incantation on Issei’s armor to prevent him from summoning Ddraig and was called out by Kunou for attacking their world, despite being a God. As Kunou’s necklace summons Ophis and Lilith, Tartarus was preparing to fight against Ophis until she clarified that she wasn’t his opponent but it was Issei Hyoudou, who has combined with his familiar Ryuuteimaru to create Apocalypse AnswerArms, which catches Tartarus’s interest and begins attacking Issei with his countless shots of godly aura but it was blocked by the Revelation Barrier. When Issei was going to use Revelation All-Range Blaster on Tartarus, he deployed defensive magic circles to protect himself, but the blast easily destroyed the defensive magic circles and Tartarus took a huge amount of damage as half of his body was blown up and he started to regenerate himself. Deciding to attack Issei head on, Tartarus used his arms to attack Ryuuteimaru's body but they were cut down by Issei’s four armed Revelation Blades, forcing Tartarus to takes a distance to regenerate his arms as he stated that he had to fight a ridiculously atrocious existence. He used his aura attacks rain everywhere in the area with Ophis and Lilith protecting everyone, and gets a lecture from Issei as Ddraig finally manifested to combine their attacks, with Tartarus shooting aura beams from his countless hands and eyes until Ddraig dodged it and managed to hit Ryuuteimaru. His arms were cut down by Issei’s Apocalypse Ascalons and he was punched in the eyes by Ddraig and chased by Ddraig until he was burned by Ddraig's flames and was eventually defeated by the combined efforts of Issei’s Revelation All-Range Blaster and Ddraig’s flames. After his defeat, Tartarus was tattered and reduced roughly to five meters and his eyes were closed.
