I think it's sort of neat how there's the whole "Fenrir" thing going on in FFVII (chiefly in Advent Children and Dirge of Cerberus). Cloud has a bike named Fenrir and apparently the wolf ornament on his clothing and his earring is supposed to symbolize Fenrir as well. I looked up a bit of info and this is what I got:
(source: FF Wiki)
The name "Fenrir" is reference to the giant wolf Fenrisulfr in Norse mythology, often known as Fenrir, who is bound by silk chains and is destined to devour Odin at Ragnarok. This is particularly interesting as Fenrir is considered by many to be a hellhound due to his link to the guardian of Nifleheim, garmr. This leads to an interesting set of coincidences, as it means Cloud, represented by Fenrir, hails from Nibelheim, named for the land of the dead, where Odin is found in Final Fantasy VII. Cloud being represented by the hellhound who devours a god may be a deliberate distinction with Sephiroth, who wishes to achieve godhood but is repeatedly defeated by Cloud.
