Lion
Lion (voiced by Dee Bradley Baker) – Steven's pet lion who resides with Steven at the temple and first appears in "Steven's Lion". He has pink fur and a star-shaped mane, possessing magical powers including walking on water, creating portals with his roars and summoning the sword of Rose Quartz, which is stored within the pocket dimension in his mane. Lion has a mysterious connection to Rose Quartz; in "Lion 2: The Movie", he knows the location of Rose's secret armory, while in "Lion 3: Straight to Video", his mane is revealed to be a gateway to a pocket dimension containing many personal artifacts of Rose's.
