Aeos

Aeos is the former Supreme Kai of Time and the leader of the Warriors in Black. She is the initial main antagonist in the Supreme Kai of Time Saga and supervisor of the Super Space-Time Tournament.

Aeos once reigned as the Supreme Kai of Time, being the one in the position prior to Chronoa. During this time, she mentored Chronoa and Mechikabura as potential successors, with Chronoa eventually taking the role.

Aeos first appeared speaking with the Warrior in Black, asking him if he saved his son. She then informs him and his fellow Warriors in Black that her time has come.

Aeos confronts Chronoa in the Time Vault over the numerous timelines, claiming she can no longer rely on her to manage the Scrolls of Eternity and that she will take them for herself. Chronoa is prepared to use all her power to stop her, but Aeos' Warriors in Black appear to prevent Chronoa from doing so. Aeos then prepares to start the Super Space-Time Tournament, gathering various warriors from each Scroll of Eternity to fight for their existences.

Aeos is later seen overseeing the tournament unfold, musing about the overflow of new timelines and how she couldn't leave the duty of Supreme Kai of Time to Chronoa any longer and was forced to step in. After the first round of the tournament is over, Aeos appears and intervenes in the battle between Xeno Trunks and the Future Warrior in Black, using the power of time to stop their attacks before sending them away through a space-time distortion.

In the manga, Aeos is later seen through a televised screen, explaining the true intent of the Super Space-Time Tournament towards Goku's team, Team 1. As she states, The Super Space-Time Tournament evaluates the fighting ability and "luck" of each individual from each point of history and who would be at Time's "Luck". as this Tournament was held to observe their fate and claims that Team 1's warriors were blessed with great luck and achieved victory. and finally, Aeos claims that what they see here, is the selection of "True History".

Later on, Aeos incinerates the losing teams' Scrolls of Eternity and personally presents herself to the winning teams, congratulating them for their success at winning the first round of the tournament and once more tells them of her true intentions, how timelines distort one another and why she has to take back her position from Chronoa once more. Angered by Aeos brushing her actions off as simply the fate those histories were destined to meet, Xeno Trunks attacks her with a Sword Blast, but Aeos snaps her fingers and causes Xeno Trunks and his attack to vanish on the spot at such a speed that neither Jiren nor Hit could follow. Everyone assumes Aeos erased Xeno Trunks, much like she did with the Scrolls of Eternity, as she reminds them all of her status as former Supreme Kai of Time. She states that when the true singular history is decided from the tournament, she will retake her title from Chronoa, much to the chagrin of the Time Patrollers who don't want a Supreme Kai who doesn't care about people. Aeos remains cold, saying that in order to maintain the balance of time, the alternate timelines had to disappear.

This is the final straw for the gathered teams, as Xeno Goten, Xeno Gohan, Xeno Pan, Hearts, Xeno Vegeta and Vegeta all begin to charge attacks at her (the latter two demanding she bring Xeno Trunks back) before firing, as Aeos leaves her Warriors in Black to intercept the blasts and leave her unharmed. Calling the Time Patrollers rebellious, she makes them disappear as well, before vanishing Hearts' group, followed by Goku's team. Unfortunately for Yamcha, he is the only member left in the area, and - panicked to all hell - tries to run off despite there being nowhere to run and begs Aeos not to erase him too. His antics actually crack Aeos up, and she reveals she didn't really erase them, only sent them to the next round during her Time Freeze. She tells Yamcha to give it his best in order to survive before teleporting him as well, starting off the second round of the Super Space-Time Tournament.

During the second round, Chronoa visits Aeos and asks that she return the Time Scrolls only for her to respond that if she wants them then she should try taking them from her and proceeds to conjure up a mass of Time Scrolls into a box and then with a flick of her fingers sends Chronoa and herself outside.

Aeos tells Chronoa that she will show her no mercy if she intends to get in the way of her plans and proceeds to transform into the Time Power Unleashed state. In response, Chronoa uses the same state though says she will not use the form to battle Aeos but merely wants to talk.

However, Aeos believes that talking is pointless and promptly attacks Chronoa with an energy blast. Chronoa holds off the blast as she tries to explain that she too is aware of the danger that increasing timelines brings but chooses to place her faith in the possibilities that the timelines hold. With exerted effort, Aeos overpowers Chronoa and knocks her to the ground.

Goku then appears with the Time Fairy in tow and checks on the injured Chronoa. Goku then turns towards Aeos and offers his thanks to her for being responsible for hosting the tournament that has given him the opportunity to fight many strong opponents but asks that she not erase any timelines. Aeos asks if he lacks the confidence to win the tournament, but Goku simply points out that there are living beings in the other timelines and erasing them would be wrong.

Aeos declines his request and attempts to use her powers to freeze him but within a blink of an eye Goku teleports behind her and transforms into his Ultra Instinct Sign state. The two battle with Goku being relentless in his attacks so as to not give Aeos the time needed to perform her magic. Aeos surrounds Goku with a swarm of small energy blasts, but Goku uses his Instant Transmission to appear right in front of Aeos before letting off a Kamehameha at point blank range. Aeos acknowledges the danger that Goku possesses and vows to eliminate him.

Before being able to make an attempt at doing so, the Time Nest is invaded by the new Dark King, Demigra, now with the Time Scrolls in his possession and with sights of a new age of fear in which he would rule. Aeos makes a temporary alliance with Goku in face of this new threat. However, the two are clearly outmatched by Demigra's newfound power, with even a Time Labyrinth being unable to hold Demigra in place.
