Since the it has been considered politically incorrect to call a black cat a black panther. The big black cats are black leopards or black jaguars and are not referred to as black panthers by anyone who knows anything about big cats.
Clouded Leopard~seldom seen in the wild. The clouded leopard is a cat found from the Himalayan foothills through mainland Southeast Asia into China, and has been classified as Vulnerable in 2008 by IUCN
A jaglion or jaguon is a cross between a male jaguar and a female lion. It has the lion's background color, brown, jaguar-like rosettes and the powerful build of the jaguar. This scares me more than a male lion!
