Ignis, nicknamed Ai by Yusaku, also known as the Mysterious Lifeform (謎の生命体 Nazo no Seimeitai) or the Mysterious A.I., is a character appearing in the Yu-Gi-Oh! VRAINS anime. He is a mysterious A.I. program sought after by both SOL Technology and The Knights of Hanoi. He was captured into Yusaku Fujiki's Duel Disk and forced to be his Duel AI.
Right from the start, Ignis can be seen as mischievous and arrogant. According to his own words, he is very disliked by his own people. Ignis struggles to understand humans' way of thinking that often seem completely illogical compared to his algorithm based way of thinking. However he can be more serious at times such as making observations both in and outside of duels. He also has a tendency to panic at times. Ignis frequently tries to interact with other AIs, showing a more social side but is always left disappointed because they're not as capable of free thinking as himself.
As an AI belonging to the Cyberse, Ignis has some degree of control over it. He is the only one who knows it's location and can unlock data from it to start a Data Storm. After being trapped in Yusaku's Duel Disk, he can also act as a Duel AI. Inside Link VRAINS Ignis is shown able to transform to a monster, which he did to devour a Knight of Hanoi member..
An AI program created by SOL Technology, Ignis was used alongside five other AI programs. Five years prior to the start of the series, Ignis took vital information about the Cyberse away from The Knights of Hanoi during their attack. Despite being crushed by a "Cracking Dragon", his eye survived. Ever since, he had been running from both the Knights and SOL Technology. Being reduced to nothing but an eye also damaged most of his memories.
While being pursued by both factions, Ignis fell into a trap created by Playmaker, who saved him by absorbing him into his Duel Disk, turning him into a Dueling AI, thus necessitating the defeat of Playmaker in order to recover Ignis. Ignis doubted that Playmaker's Deck was strong enough to defeat the Knights' "Cracking Dragon" before stirring up a virtual wind called "Data Storm" that initiated a Speed Duel. Before the Duel began, Ignis explained Playmaker how Speed Duels worked but didn't mention Skills. Through out the Duel Ignis repeatedly tried to offer support for Playmaker, only for Playmaker to keep telling him to shut up and remind that he was holding Ignis hostage. When they sucked into a tornado within the Data Storm, Playmaker figured out that Ignis not mentioning skills and bringing him to the tornado was part of his calculations.
Ignis confirmed this, and activated Playmaker's skill "Storm Access", which allowed them to obtain "Decode Talker" so Playmaker could defeat the Knight. The Knight attempted to self destruct and kill Playmaker, but Ignis turned into a monster and devoured the knight to save Playmaker. He suggested Playmaker should log off soon. Yusaku and Shoichi Kusanagi spent the next few days trying to figure out Ignis' programming. Since Ignis was always noisy, Yusaku has the speaker turned off so he didn't need to listen to his ranting. Kusanagi suggested giving Ignis a nickname, and Yusaku nicknamed him "Ai" since he is an A.I, much to Ignis' dismay. Eventually Yusaku found footage from some of Ignis' memories, which Ignis himself didn't understand except for Revolver being the leader of Hanoi. Scanning those recordings caused Revolver to sense Ignis and try to find him, but Shoichi shutting off Café Nagi's power prevented Revolver from finding them. The next day, Ignis was left at Yusaku's house, there he tried to convince Roboppy to set him free by promising to make him a better A.I. Ignis panicked when Yusaku returned home and had roboppy put him back on the shelf. When Yusaku found them, Ignis told Yusaku that had arrived home early, to which Yusaku said a Knight of Hanoi appeared and revealed a secret room he uses to go to LINK VRAINS. As soon as they arrived, both Playmaker and Ignis quickly figured out the Knight was fake. The "Knight" revealed himself to be Go Onizuka, who wanted to challenge Playmaker. Ignis looked up information about Go, Playmaker was uninterested and attempted to log out but a program from SOL prevented him from doing so, so he was forced to Duel Go. During the Duel, Ignis continued researching Go and found out that Go donated most of his money to the orphanage where he grew up. When Go let himself take 2000 Damage when he had the chance to avoid it, Ignis was confused about why humans make illogical choices. Playmaker said it was because of their hearts, but didn't explain what that meant because Ignis' algorithm-based thinking wouldn't undertand it.
