Vice Admiral Kaiser Moustache is one of the many Marine officers to have participated in the Battle of Marineford.

Appearance
Kaiser Moustache is of average height and well built. His most distinctive feature is his handlebar moustache. His hair is black and combed back with a scalp lock. He dresses in the typical garb of many high-ranking Marines: He wears a yellow and black striped suit over a dark red shirt with an orange tie. He wears a marine coat hanging from his shoulders like a cape.

Abilities and Powers
As a Vice Admiral, Kaiser Moustache is capable of commanding a Buster Call alongside four other Vice-Admirals. He also has command over lower-ranking subordinates.

Weapons
He is seen carrying a katana during the War of Marineford, like most of the Vice Admirals. His exact level of swordsmanship remains unknown; however it is presumably quite high, with him being a Vice Admiral.

Haki
It was stated that all Vice Admirals possess Haki, so Kaiser Moustache can also use the ability. However, he has not yet been shown using it.

East Blue Saga
Moustache first appeared when the Marines were having a meeting in Marineford.

Jaya Arc
He appeared when the Marines were having a meeting in Mariejois to determine a new Shichibukai after Crocodile's dismissal. An officer was then manipulated by Donquixote Doflamingo to attempt to strangle Moustache. He struggled against the officer, not knowing that it was Doflamingo's doing. The quarrel was stopped by Sengoku's arrival.

Marineford Arc
When the execution of Portgas D. Ace was announced, Moustache reported to the summoning of the Marines to reinforce Marineford. Later, he was seen with his fellow vice admirals lined up and ready to fight the Whitebeard Pirates. When the Whitebeard Pirates advanced into the plaza, Moustache ordered his underlings to attack Edward Newgate. When Luffy is trying to get to the execution platform he ordered Marines to stop him. Upon Shanks' arrival and truce was declared, Moustache stood down under Sengoku's orders.

Trivia

 * His name means "handlebar moustache". It is unknown whether this name is his real name.
 * Since his name came from the anime instead of the manga or databooks, it cannot be considered canon, despite him being a canon character. However, it is possible that Oda informed Toei of his name, since all of the New World Allies' names were revealed in the anime, before the fourth databook came out.
