Snake! You can't do that! The future will be changed! You'll create a time paradox!!
--Roy Campbell, Metal Gear Solid 3
A picture depicting a chronologically impossible scenario. Usually means at least one character appears twice in the same scene, such as a character meeting an older or younger version of himself/herself or of another character who is ostensibly his/her age, but can also mean two characters together who are explicitly from different time periods (or perhaps commonly seen in different time periods -- an ordinary picture of Asahina Mikuru together with Kyon doesn't count as this tag, but a picture of Mikuru meeting her adult form does). Another example would be Revolver Ocelot meeting Major Ocelot, or Altair meeting Desmond Miles.
