(CNN) A burly kangaroo whose buff physique shot him to internet fame has died at the age of 12.

"We have lost our beautiful boy, Roger," Chris Barnes, owner of the Kangaroo Sanctuary in Australia, announced on Saturday on Facebook.

Roger, who was 6 foot 7 inches and weighed nearly 200 pounds in his prime, was rescued by Barnes as a joey after his mother was killed on a highway.

In a video tribute to the marsupial, Barnes said he was inspired to set up the 188-acre sanctuary in Alice Springs to house the famous kangaroo and his growing harem of wives.

"I built it so they had a place to live," he said. Roger was the sanctuary's alpha male for many years, Barnes added. "He grew up to be a kangaroo that people from all over the world have grown to love as much as we love him too."
