DON'T take this seriously. I took a lot of liberties with this, I know, but this is how I wanted to draw it. Draw your own version if you feel a need to make a more correct one.
Loki you whore!
The big snake in the back in the Midgard Serpent, the wolf is the Fenris Wolf, the half-dead looking woman is Hel (guidian of the underworld), all of whom he had with a jotun woman (or Ice Giantess. God I hate the English word for jotuns)
The horse is Slejpner whom Loki gave birth to in the form of a female horse himself, the troll is one of the troll women he also birthed, apparently in the form of a human man.
The two normal looking boys are Narfe and Vale whom he got with his wife Sigyn. They're not too normal though, as one will be turned into a wolf later and accidentally kill his brother.
I thought about adding a random human too, because apparently he had sex with a ton of men in the form of a human female and gave birth to quite a few children on earth, but I couldn't be bothered.
