Disappeared
Also known as Grimace of the Notch Boys · The Youngest Notch Son
c. 2005 – 2013
Born in Musiara Marsh area, Masai Mara, Kenya
Grimace was a male lion of Kenya’s Masai Mara and the youngest of the five sons of the legendary Notch. He was born into the Marsh Pride, the pride made famous by the BBC’s Big Cat Diary, while his father was its king, and he grew up as one of the six males of the Notch Coalition, the rare father-and-sons alliance that dominated much of the Mara for about a decade. Lion followers remember him for his lighter, blonde-tinged mane, which he shared with his brother Mighty Long, and for the expression that gave him his name.
When Notch was driven out of the Marsh Pride around 2007, Grimace and his brothers, Notch II, Mighty Long, Ron and Caesar, were only about two and a half years old. They left with their father and, as they grew, took over pride after pride, including Fang’s River Pride at Rekero, the story told in Disneynature’s African Cats. According to one account told by lion followers, Grimace was at first called Bob, and earned his new name after his lip was torn in the fight for the Maji ya Fisi pride, which he reportedly led his brothers Notch II, Ron and Caesar to take while Notch and Long stayed behind.
In 2013 Notch disappeared while patrolling his territory. A few months later Grimace vanished during one of his excursions into a rival coalition’s territory in search of new lionesses, and he was never seen alive again. Accounts of his end differ: some lion followers say his remains were found later, possibly in 2015, with wounds that may have come from the horns of an eland. His three remaining brothers carried on without him.
A grimace is a twisted facial expression. He was reportedly given the name after his lip was torn in a fight, which left him looking as if he were grimacing.
One account by lion followers says he was called Bob before the fight that gave him his better-known name. This is not confirmed.
The same name spelled with a double m by some lion followers online.
He is widely described as the youngest of Notch’s five sons.
Born in the Marsh Pride, the youngest of five sons of Notch, the pride’s king.
Romeo and Clawed drove Notch from the Marsh Pride. Grimace, about two and a half years old, left with his father and brothers.

According to lion followers, he led Notch II, Ron and Caesar to take the Maji ya Fisi pride. His lip was torn in the fight, and from then on he was known as Grimace.
The coalition took the River Pride at Rekero from Fang, the story told in African Cats. His brother Mighty Long disappeared.
The Notch males were reported to control five prides in the eastern Mara.
His father Notch disappeared while patrolling the coalition’s territory.
A few months later, Grimace vanished while searching for new lionesses in a rival coalition’s territory, and was never seen alive again.
Some lion followers report that his remains were found, with injuries possibly caused by an eland’s horns. This has not been confirmed.
Most accounts say Notch disappeared first and Grimace a few months later. One account by lion followers tells it the other way round: that Notch never returned from searching for his missing son in enemy territory in mid-2013. The true order is not known.
Because Grimace and Mighty Long had lighter manes than their brothers, some lion followers believe they were fathered by Notch’s first coalition partner rather than by Notch himself. No genetic testing has ever been done.
A safari writer described Grimace killing a cub brought near the brothers’ kill by a lioness from outside their prides. Hard as it is to watch, killing the cubs of rival males is normal behaviour for male lions.
