Simeon

Simeon is an E.S. unit that appears in the Xenosaga series. It is piloted by Albedo.

Description
Simeon was originally built in Labyrinthos. It is equipped with a long tail stabilizer functioning as its logical drive. It specializes in high-mobility combat. It is able to deal with any type of battle situation including both short and long range.

Upon becoming a testament, Albedo swaps his Vessel of Anima into a new unit also called SSimeon which has similar specifications.

Episode I
Simeon is used by Albedo when he visits Pleroma and is used by him for transportation throughout the remainder of the game, when he heads to the Kukai Foundation, Song of Nephilim and Proto Merkabah. He is at times accompanied by a Kirschwasser co-pilot. The party does battle with Simeon while at the Song of Nephilim, with Albedo retreating afterwards due to the appearance of the Blue Testament.

Episode II
Simeon continues to be used by Albedo until he opens the path to Old Miltia. At the end of the game when Albedo is welcomed by Wilhelm as the White Testament, he appears atop a redesigned version of Simeon, which is no longer humanoid in appearance.

Episode III
Simeon appears on the Floating Landmass when Albedo arrives to recover Virgil after his E.S. Naphtali is defeated by the party. It recovers the Vessel of Anima from Naphtali. Its older model is found by the party within Labyrinthos when they seek to steal the Vessels of Anima.
