A great 'lie to me fanfiction' could be set in a different time period, like the 1920s. The characters would have to adapt their lie - detecting skills to the social norms and technology of that era. They could be involved in a case related to the underground speakeasy scene, where lies and secrets are rampant, and they have to navigate through a web of deception to solve the mystery.
One common theme is the idea of deception. In both shows, characters often have to deal with lies, whether it's demons lying in Supernatural or people lying in Lie to Me. So in fanfiction, this theme is often explored more deeply, like how the characters from one show might handle the types of lies common in the other show.
One great 'Lie to Me' OC fanfiction is 'The New Observer'. It has an interesting original character who brings a fresh perspective to the team. The plot is engaging as the OC tries to prove their worth among the regular characters.
A really well - written one is 'Supernatural Deception'. It takes elements from Lie to Me such as the ability to read micro - expressions and uses it in the context of the Supernatural universe. The story has a lot of twists and turns as the characters try to navigate through a web of lies spun by demons and other supernatural creatures.

I'll share this. There was a boy who had a backpack that could take him to any place in the world just by him thinking about the destination. But that's a lie. In real life, we need to use various means of transportation like planes, trains or cars to travel long distances.
