Talk:Ice Blade, Joker/@comment-3493584-20140927002754

hm, Ok this might be a bit of a stretch but he could be Loki (or possibly retroactively made into the buddy fight loki when they decided to put him in asgard).

Loki was originally a frost giant (fitting the ice part of the name)  before becoming odins blood brother and a god. he was also the god of tricksters (represented by the joker in his name), participated against the gods in ragnarok, and was the fatehr of fenrir, who ice blad joker works in tandem with as part of asgards ragnarok combo.

I'm not that well versed in norse myth so I couldn't really say what other figures from those myths would be a more likely inspiration.
