The Guardian Force cards are a series of Synchro Monsters use by The Guardians in the Yu-Gi-Oh! 5D's: Force of the Guardians fanfiction series. Each card represents the original soul of their owner, because the current Guardians are the reincarnations of those Guardians. There is a total of 23 Force Monsters, one for each of the elements of the world and life that each Guardian represented. Each Force has the Kanji for their element somewhere on them.
