Penny Polendina[1] was a character who was introduced in the episode "The Stray", when she was found lying on the ground after Weiss Schnee crashed into her, whilst chasing after Sun Wukong.

In "Painting the Town..." it is revealed that Penny was a robot, with her telling Ruby that "most girls are born, but I was made".

In "PvP", Penny is killed by her own weapon when Pyrrha Nikos used her polarity Semblance to deflect what she thought were thousands of Penny's swords coming at her, when in reality it was Emerald Sustrai using her perception manipulation Semblance to trick Pyrrha into using her Semblance to a devastating magnitude.
