Last night I was unfortunate enough to watch a film starring David Hasselhoff called Nick Fury: Agent Of S.H.I.E.L.D. It was one of the most poorly made and clichéd film I've ever seen, second only to Street Fighter (Jean Claude Van Damme and Kylie Minogue). However, suffice to say there was one thing that was mentioned that made me prick up my ears. This secret government organisation, S.H.I.E.L.D., has various departments, and one of them is comprised of people with extra-sensory perception (ESP for short). They called themselves ESP'ers, or Espers.
This made me think back to the sequence between Terra and Ramuh in Zozo when they are communicating using telepathy. Could it be that Espers are indeed people with extra-sensory perception that were locked away due to their power?
