Fate unknown
Autumn
Also known as Summer’s Sister · Co-leader of Summer’s Pride · Nat Geo’s LION
Filmed c. 2021 – 2025
Born in an unrecorded place
Autumn is the name National Geographic gives to one of the three sister lionesses who lead the pride at the centre of LION, the four-part series filmed over four years in Kenya’s Masai Mara and released in August 2026. With her sisters Summer and Winter she is introduced as one of the queens and leaders of a sprawling pride, one of the largest in the Mara.
In the series the three sisters share the work of the pride: hunting, guarding the nursery and raising the cubs together. When Summer’s small cub Kio was pushed around by his larger relatives, it was to his mother and her sisters that he turned for comfort.
Beyond her role in the series, very little about Autumn has been published: not her guide name, her age, her cubs or what became of her after filming. This record will grow as more becomes known.

Legend & Truth
Little is known
Autumn is a secondary figure in the series, and National Geographic has published almost nothing about her beyond her role as Summer’s sister. Many sections of this record are marked as not available for that reason.
