Leo the Lion

Leo the Lion is a former MGM (later Goldwyn) and the former.

Leo, the seventh lion, is by far MGM's longest-used lion, having appeared on most MGM films since 1957. Leo was born in Dublin Zoo, Ireland, the same as Slats. He was also the youngest at the time MGM filmed him roaring (hence his much smaller mane).

after DreamWorks' The Boss Baby lost Best Animated Feature to Disney/Pixar's Coco both at the 90th Academy Awards and the 44th Saturn Awards, MGM announced that it will change it's Lion.

due to the death of SpongeBob SquarePants creator Stephen Hillenburg, MGM will decide to keep this lion for two years, until Taxi the Lion replaced Leo The Lion (due to Discovery Inc. buying MGM).
