Loki

Loki is a shapeshifting jerk of a trickster god, who always takes pranks much too far. Loki was imprisoned in their own son's entrails for secondhand murder. They spend a lot of their time watching people try to portray them in popular media, before assuming their forms and acting as themself in movies and TV shows. Loki was broken out of their shackles by Lucifer a couple years back, but has been continually pressured to start Ragnarok by Shiva and continually traumatized by Odin to stop them from starting Ragnarok.

Early in life, along with the other Aesir, Loki made a deal with Ragnarok Life Insurance to make themself effectively immortal, until a certain criteria was met. In this case, the end of the entire world in a climactic battle. Now that they're free, they flip-flop between wanting the world to end as vengeance on the Aesir for murdering their son and imprisoning them for several thousand years, and toying with the world because it's fun and they don't particularly want to die just yet, especially now that they're free.

As of Season 2, they're trying to get Ragnarok done while also spending quality time with their partners, Sigyn and Angrboda and learning from Primetime to be a better person.
