I have a Loki. This Loki is from the comics, specifically after the Agent of Asgard run from 2014. He just saved his universe (...sorta) by making it a story and saving it as one and was turning a new blank page to see what life would offer next. He will be very surprised to find himself here!
Depending who's labeling him, Loki is the trickster god(dess) of Mischief, Chaos, Lies and Stories and the Moon-King. Others might call him much less charitable things. He'll probably just call himself Loki, thanks.
Loki is, in essence, mischievous by nature but not particularly evil even if he might come across as such on occasion -- if only because he's very, very good at scheming and sort of does it without considering consequences. In any case, he's both very old and very young in this incarnation and he acts it sometimes.
