Genesis

Genesis (ジェネシス) is a game adaptation-original character introduced in Sword Art Online: Hollow Realization. He is known as the «Black Swordsman» (黒の剣士) by the players of Sword Art: Origin. It was later revealed that he is in fact a famous hacker known as the «God of Cheats» (ゴッド オブ チート).

Personality
Genesis is known to get strange looks when he is fixated on battle and he enjoys stealing the hard-earned kills of other players.

Hollow Realization
While Kirito and Argo were attempting to clear the second area of Ainground, Genesis was surrounded by other players, who angrily complained to him for stealing their kills, but he only mocked the players before departing.

After rumors of Kirito saving a Non-Player Character (NPC) from being sacrificed to a monster by other players spread, Genesis decided to see Kirito for himself. When challenged to a duel during their encounter, Genesis rejected the request, deeming Kirito to be not worth the effort.

Later, in the field, Genesis was in battle with a dragon when Kirito's group encountered him. As Genesis was overwhelmed, Klein offered to assist, but Genesis rejected the offer. He then performed a mysterious action with his in-game menu, before reengaging the dragon in combat and defeating it.

While traversing the third area, Genesis defeated a monster that he believed was the Area Boss, and thus quickly spread word of his deed. His glory was short-lived, however, as he soon realized that the enemy he had fought was a decoy, while the real boss was dispatched by Kirito's group. Angered by this, Genesis approached Kirito in town, telling him of his belief that only the strong were meant to rule in the virtual world.

At a later time, Genesis encountered the other goddess meant for Premiere's original quest. While Genesis was secretly spying on Kirito's group after this encounter, he discovered the truth about the Grand Quest by witnessing their hack of an administrator console in the desert area.

By the time Kirito's group arrived at the location of the fifth Sacred Stone, Genesis had already found and claimed the stone with the aid of the second goddess. Before departing, Genesis informed Kirito of his plan to finish Premiere's quest and enjoy watching the new Aincrad burn to ash.
