XJ-5 is a radio-like prototype XJ robot with a satellite dish for a hand, one of the XJ sisters created by Dr. Noreen Wakeman.
XJ-5 is the literal chatterbox of the XJ-Sisters, though she does have great leadership skills, seen when she managed to lead her sisters in fixing a dam in Sibling Tsunami. In Turncoats, when she is being controlled by Dr. Locus’ remote, she doesn't speak, but instead plays music like a radio, even playing taps when she is defeated.
