Keyonne Greyson

"The moment I stop seeing people as individuals, but as "whites" or "aristocrats" or "bourgeoisie", I become no better than the people who once oppressed me."

- Keyonne's ideology

Keyonne Greyson, known mononymously as Keyonne throughout the Autistic Adventures series, is the primary antagonist for the first two parts of the novel, before becoming a supporting protagonist towards the conclusion of the second part.

Biography
Keyonne was born to Keith and Gloria Greyson, twenty-two years before the start of Autistic Adventures in a backwater country in Afrika called Zahanna, and was chosen to be the vessel for Ajit Pai's soul. Being constantly ostracised throughout his life for being born magic-less and having a peasant-like social status, Keyonne developed a jaded view of the world since he was young, believing it was corrupt for favouring the undeserving stronger minority over the weaker majority that work diligently. Following a traumatic event after he returned to his home country after studying abroad in Ruthenia, Keyonne awakened the Dark Lord's soul within himself, quickly amassed an army, and declared war on the Wizard Realm. With the help of Andrei Krakowski, Sydney Smith, and Hamdan Sheik, Keyonne was able to conquer a large portion of the realm within two years, before finally being recognized by the realm's overseer, Alan Xian, as a serious threat. Following multiple defeats that resulted in a year-long stalemate between his forces and Alan's, Keyonne grew wary of the prophecy of "the Peterphile", and was involved in the later events of Autistic Adventures.

Although he survived his duel with Alan during the Battle of the Holy Library due to his predecessor's intervention, Keyonne was wounded to the brink of death. Besides losing his right arm, most of Keyonne's internal organs were damaged beyond repair even by magic. His life was preserved for the next two years through the Chrono Capsule he invented that suspended him in time, during which his subordinates performed medical surgery on him and built a rudimentary life-sustaining suit of armor to seal him in. Upon awakening from his coma after he was put into the armor, Keyonne withdrew himself from the frontlines and instead focused on inventing more technologies and secretly recruiting more members across the realm. Almost an entire year later, outfitted with a new Cape of Darkness and an improved suit of armor, Keyonne and his remaining forces attacked the Holy Library, defeating its overseer Li Shimin and enlisting him into their forces while revealing the existence of the Library to the public. The news of this victory incited uprisings in support of Keyonne's army—now named the Nigaboos—around the realm, greatly increasing their territory compared to three years ago.

Keyonne was widely considered deceased by non-Nigaboos affiliates, including the Empyrean Embers. He was responsible for the death of Peter Yan during the Raid on Area 51, and was the mysterious man who nearly defeated Christian Price in the Smash Bros Tournament during the Game-Land Civil War. After the successful capture of Mizutsune, Astalos, Gammoth, and Glavenus following the Battle of the Kingdom of Beasts, Keyonne would manage to gain the trust of the four Tailed Beasts after revealing to them his ideology, which resonated with their hatred for humans. Mizutsune, in particular, would develop romantic feelings for Keyonne. His livelihood would later be revealed during the Battle for Greatbug, where he actively fought against Greatbug and prevented Michael Hitler's self-destruction.

Near the end of Actually-Good Shippuden, Keyonne accepted Li's deduction of the Empyrean Ember's strategy and formulated a countermeasure. On the day of the Liberation of the Holy Library, while most of the Empyrean Embers, joined by Game-Land's military, the Kingdom of Beasts's Animal Army, two Tailed Beasts, and the armies of miscellaneous countries across the Wizard Realm launched an invasion on the Nigaboos' headquarters, Keyonne evacuated and secured the Holy Library while sending off the remaining guards to "reinforce" the troops in Zahanna. Eventually, Peter appeared to reclaim the Library, who Keyonne confronted after he entered the building. The duel between the Second Dark Lord and the Peterphile ensued within the Holy Library's arena, and Peter was promptly defeated after being overwhelmed by Keyonne's superior physical abilities and combat techniques. Instead of using the opportunity to kill Peter, Keyonne treated him with food and had a conversation with him. Although awkward at first, the two archenemies slowly began to understand each other after Keyonne revealed his backstory. Understanding each other's perspectives and ideologies, Peter and Keyonne made an agreement to end the Second Dark Lord War and work together to make the Wizard Realm better. Just when the alliance was formed, the Holy Grail was activated as Li successfully obtained the remaining three Legendary Weapons from the Empyrean Embers and inserted them into the device. The magic energy provided by the Weapons was teleported to the Holy Library and absorbed by Keyonne, healing his untreatable injuries and regenerating his arm.

The spike in magic energy unintentionally drew the attention of the Elysapien Empire, allowing them to discover the Wizard Realm's existence and subsequently pinpoint Earth's location. With Archangel Shuwartz's Dimension Magic, the Imperial Elysapien Army immediately arrived at Earth, and attacked the exhausted forces at Nigaboos headquarters. After receiving a brief report, the two headed towards the battlefield, with Keyonne arriving later after gathering all his remaining troops stationed elsewhere and setting up cameras to broadcast the battle throughout the Wizard Realm. Ultimately, with the reinforcement of many armies across the Wizard Realm and its inhabitants support, the Elysapiens were defeated.
