Grimlock

Grimlock is one of the 10,000 players who were trapped in Sword Art Online and a former member of the guild Golden Apple.

Appearance
Grimlock wears dark clothing and a hat. He also wears glasses. He is relatively tall and his dark clothing gives off an aura of mysteriousness. Grimlock has short hair with long bangs.

Personality
Grimlock had apparently loved his wife, Griselda, greatly. However, unlike Grimlock who was constantly scared of death, Griselda did not fear death as she played Sword Art Online and was notably more lively living in the game than she was in real life. Grimlock apparently felt that Griselda had loved the game more than her husband and, in possibly desperation due to the fear of death, he killed Griselda as he beleived she no longers resemble the wife he loved in real life.

Background
Sometime in the past before the events of SAO occurred, Grimlock married Griselda and they were happy together for a while.

Murder Case in the Area
He was the culprit of his in-game and real-life wife, Griselda's death. He killed her because he did not like the change in her personality. At first he didn't want to aid Caynz and Yolko in their plans to catch Griselda's killer by forging them weapons to use in the in-AREA murders, but eventually he did, but not with good intentions. He helped so he could have Caynz, Yolko and Schmitt together and get them killed with the help of the infamous red guild, Laughing Coffin. However, the plan failed, because Kirito realized the truth of Griselda's death in time, and came to rescue Caynz,Yolko and Schmitt. Grimlock is then caught by Asuna.

It is unknown to what happened to him in the remaining time of SAO, but in the end, he is assumed to be logged out.

Trivia

 * In the fourteenth episode of the anime, his name appears briefly as one of the players who logged out.
