Panther is a panther made of some type of stone. She first appeared in The Unwanteds: Island of Legends. She is a bit smaller then Simber and is slightly younger. 

She was originally created by Marcus Today as a companion for Simber, but due to some flaw, she was moved to the jungle. Aaron Stowe later discovered her, and she inadvertently killed Eva Fathom.

Panther seems to lose her tail, which can be fixed by attaching a vine. She screams whenever she is happy, and is revealed in The Unwanteds: Island of Dragons that Simber has feelings for her, she might have them for Simber, as she screamed in his face.
