In the original free-to-play versions of the game, Raiden's signet could only be obtained through the game's summon draw shop and could be equipped by any party member.
According to the official description of the summon from the free-to-play versions, Raiden is described as an upgraded variant of the Odin Eidolon, referring to Raiden being an upgraded version of Odin in Final Fantasy VI. Raiden's artwork is based on the summon's in-game sprite from Final Fantasy VI, while taking design elements from its original artwork by Yoshitaka Amano.

Raijin, also called Raiden, is a god of thunder and lightning in Japanese mythology.Raiden is the Chinese/Japanese word for the physical phenomena thunder and lightning.
The Japanese word Raiden (雷電?) is written ライデン? in katakana. The summon's name is instead ライディーン (Raidīn?). One possible source for this name is that it is a mix of "Raiden" with "Odin": In Final Fantasy VI Odin (オーディン, Ōdin?) does not extend the ディ (di?) sound, however there are other times in the series Odin's name has been written オーディーン (Ōdīn?).
There is a 1976 anime series called Brave Raideen where the titular mecha is named Raideen (ライディーン, Raidīn?). Yellow Magic Orchestra has a track called "Rydeen" from the 1979 album Solid State Survivor. The track is known for having been sampled and covered in many early Japanese video games, and drew inspiration from the rhythms of a running horse. The name for the track has been officially transcribed into Japanese as ライディーン (Raidīn?) (and also as 雷電?, the same kanji for Raiden).
- Despite being described as an upgraded form of Odin, Raiden's signet is not equipped to Odin when he joins the party as a guest during the finale of the Eureka arc.
