Boko

Known as Boko in later versions, he is the protagonist Bartz Klauser's chocobo and faithful friend. Boko has a brief appearance in Bartz's world when he helps Bartz rescue Lenna and Galuf, but becomes more important further into the storyline as the party is able to ride him around more frequently.

In the merged world, Boko meets a female chocobo named Koko and they have children together. Bartz is amused by his bird's virility, calling Boko a "stud". Boko also appears in a tutorial by explaining the job system and abilities, after the player obtains the ability to change the party's jobs.
