Dinah

Dinah is a playable E.S. unit that appears in the Xenosaga series. It is primarily used by KOS-MOS.

Episode II
Dinah was a transport craft developed by Kevin along with KOS-MOS. It was being stored on the Dämmerung. When Shion seeks to head to Old Miltia, she and Allen steal it and head into hyperspace. Meanwhile on Second Miltia, KOS-MOS awakens on her own and departs on her own craft, saying Shion is calling her. Once she has caught up with Shion and Allen, KOS-MOS docks with the Dinah, forming its humanoid form (called Control Mode B). Using it, she fights off Dan and the other enemy crafts in the area. KOS-MOS uses it as her E.S. for the remainder of the game, with various other characters acting as a co-pilot.
