Eugene

General Eugene (ユージン) is the head of the Salamander armed forces and later the New Aincrad clearing army. He was considered the strongest player in ALfheim Online until he was defeated by Kirito in a one-on-one duel during the Conference of the Cait Sith and Sylph lords.

Background
He is Lord Mortimer's brother in-game and in real life as well. He uses the second most powerful weapon in the game, the Demonic Sword Gram.

ALfheim Online
General Eugene intended to disrupt the Cait Sith and Sylph alliance conference. Earlier, Recon manages to learn of the attack and warns Leafa. She and Kirito rush to stop the confrontation, but Eugene challenges the Spriggan to a one-on-one duel. At first, Kirito was forced to defend himself against the onslaught of the Earth-style weapon of Eugene, but Kirito takes Leafa's katana to prepare for his notable Dual Blades. With this extra blade, Eugene could not breach Kirito's defenses and was quickly defeated. After the duel, he was revived by Sakuya and leaves the scene with his forces on good terms.

He later visits Kirito's and Asuna's home, unfortunately, conciding with Sakuya's visit. The entire visit was noted to have been very tense.

When the New Aincrad is released, he is shown to be the head of the Aincrad clearing force and once again faces Kirito on Christmas Eve to test the Excaliber.
