Boekind

Boekind was a species from the Silver Devastation in the Isop Galaxy.

Biology
Boekind were large, humanoid heads with numerous tendrils which terminated in round pod-like structures in place of hair. (DW: The End of the World)

It is aso known that Boekind can only grunt vocally, yet they can communicate very well telepathically and can even properly speak. (DW: The End of the World, New Earth, Gridlock)

Life Cycle
Little is known about Boekind reproduction, but it is known that they could become pregnant and can give birth to at least 6 infants. (DW: The Long Game)

Technology
The only technology known to be used by Boekind was a life support tank with added teleport in which the Face of Boe lived in permanently, however even this may be not have been created by Boekind and may be a creation of another race. (DW: The End of the World, New Earth, Gridlock)

History
The fist of Boekind, the Face of Boe, was originally Jack Harkness. After the Battle of the Game Station, the Bad Wolf entity made him near-immortal. Eventually, he started to age, albeit very slowly. The ultimate outcome of this was the Face, so named because that was one of Jack's nicknames, as he was born on the Boeshane peninsula. (DW: Last of the Time Lords)


 * Presumably, Jack time traveled back to the Dark Times, as Boekind were known as an ancient species, having originated in the Isop Galaxy "when the stars of the Andromeda galaxy were still dust". (DW: Bad Wolf)

In the year 200,000, the Face gave birth to six children, the Boemina, although in 40 years time even the Boemina would die (DW: The Long Game). The Face later nearly died in the year 5,000,000,023 but managed to survive (DW: New Earth), but later sacrificed himself to save the inhabitants of New New York in the year 5,000,000,053.
