Delatron

Lady Delatron was a former simularity-star and chart-show host and third-richest woman in the cosmos. The thief Fergus Antelect tried using the telepathic abilities of Ood Delta to steal from her without her even remembering during a stage performance at the Galactic Royal Hotel, but the Tenth Doctor used Delta's telepathy against Antelect to trick Antelect into revealing he had done it.
