Shout Out / Mobile Suit Gundam 00

  • The series creators seems to be huge Square Enix fans.
  • A fan video reveals the possibility that 00 Gundam's combination sequence with the 0 Raiser is a homage to GaoGaiGar's Final Fusion sequence.
  • Both Exia and 00 Gundam/00 Raiser are seen using swords that double as rifles. 00 Raiser's are even called GN Rifle Swords, which is just a fancier way of saying "Gunblades".
  • The A-Laws' Shako caps look exactly like the ones worn by Britannian military members.
  • The second season ends with the message "The childhood of humanity ends", which is a reference to Childhood's End, a novel in which a benevolent alien race comes to Earth and guides humanity into a singularity of consciousness, providing some vague foreshadowing of the events of the movie for those who get the reference.
