1) In "TRON: Legacy", ISO is an acronym for "Isomorphic Algorithm", a life form that spontaneously emerged, without planning, from the conditions that existed in the grid at that time. 2) A term for a really really hot chick. This is adapted from the 2010 film "TRON: Legacy" because Quorra, the last ISO played by Olivia Wilde, is so unbelievably hot.
