Body bepple (or body beppling) was a physical alteration of a body that changed a person's appearance into a new and sometimes alien form. It was a fad in the 30th century. At least one person used it to have the appearance of the famous singer Elvis Presley.
Chris Cwej, one of the Seventh Doctor's companions, had undergone a body bepple to make him look like a teddy bear. It also gave him sharper teeth and nails than a human.
Although icaron particles caused paranoia in humans, those who underwent a body bepple were particularly at risk. (PROSE: Original Sin)
