 was a gestalt being that worked in the same work camp as Ian Chesterton and Barbara Wright. Another part of them was in a cell with the First Doctor. They good speak English due to a low level empathic telepathic. They crashed on Urth because of the humans and 14 of their bodies were killed by their human captors. They told Ian and Barbara about the diseased humans. They thought that Ian was stupid for wanting to go outside the spaceship. They saw the remnants of one of their other selves after the torture.
