Loki Headcanons:

Earth was Loki’s own personal playground for centuries. A sanctuary if you will filled with exploitable mortals to mess around with. But it wasn’t all mischief and mayhem.

Whenever there was some sort of civil unrest or revolution you can bet Loki was probably pulling the strings somewhere. 

Over the years he made many friends, including Wolfgang Amadeus Mozart, Lord Byron, Mae West and Keith Moon. To this day Thor can’t figure out why they drove a Rolls Royce into the Well of Mimir after a particularly heavy drinking session…

He had a brief but passionate affair with Katherine the Great. 

Some say he worked for the Nixon administration. Others vehemently deny it.

He got into punk rock in a big way which helped him win a rock off against some dark elves.

And then Thor went there for two days and Earth suddenly became all the rage! Bloody typical!

However they both got so drunk that neither of them remembered it happening.
