Judy (ジュディJudy), is a character in Mother 4: The New Pig King, and Gavin's sister. She was taken away from her home by Winston and the Pigmask Colonel and then reconstructed into a robotic chimera. Although Gavin attempts to save her, he falls short and continues to look for her after three months have passed. She is met at the top of the Mayor's Building at Castle City twice, both before the three year gap and after, later turning from having almost unnoticable robotic attributes to being fully mechanized.
