The Children of Loki

Warning: This may be a bit sad since the Aesir were extremely cruel to Loki's kids

primarily from fear and cause they hated Loki.

Loki is the guy in front and this also includes a troll woman which he may have also created
but I couldn't find a concrete answer so I don't include them.

Hel- Daughter of Loki and Angrboda

She's often depicted as either being half dead, half alive or half ugly, half beautiful. She's the ruler of Hel located in Niflheim and is seen as the goddess of death. All of those who didn't die in battle and subsequently went to Valhalla, went to Hel after they died. She actually gets the better side of things, in concern to Loki's kids, as Odin appoints her to this job and pretty much leaves her alone after that. 

Recently, I saw Thor: Ragnarok and coincidentally this was my next planned post. As much as I love the movie and completely understand that Marvel isn't going to keep to Norse mythology, the mythology nerd in me half the time was like "How about no?"

Jormungand- Son of Loki and Angrboda

He's Hel's brother and also a giant sea serpent. Odin tossed him into the great ocean that encircles Midgard. Jormungand encircles the earth with his tail held in his mouth. He tends to be the most popular example of an ouroboros. It's said that when he releases his grip, Ragnarok will begin. There, he and Thor, his arch-enemy, will fight to the death. Thor will slay, but will only make it a few steps before succumbing to his venom.

Fenrir- Son of Loki and Angrboda

He is the brother of Hel and Jormungand. He is also a giant wolf. The gods were terrified of what he might do and bound him. However, every rope and chain broke so the dwarves created Gleipnir, a magical ribbon. It was made of the sound of a cat's footfall, the beard of a woman, the spit of a bird, the breath of a fish, the roots of a mountain and the nervousness of a bear. They also say these things don't exist since they were all used in the making of the ribbon. In Ragnarok, he will actually kill Odin, but will then be killed by Odin's son, Vithar.

Sleipnir- Son of Loki and Svadlifari

Loki became a horse to distract a builder's horse, because the gods didn't want to pay said builder, and subsequently got pregnant. Sleipnir, the horse with eight legs, was born. Despite being Loki's son, Odin took the horse for his own because he was the "fastest and best of all horses."

Narvi and Vali- Sons of Loki and Sigyn

Their story is sad since they were punished only because their father, Loki, helped to kill a beloved god. Due to this, the Aesir turned Vali into a crazed wolf. He promptly attacked and subsequently killed his brother, Narvi, at the Aesir's insistence. There's no real mention of Vali after this, but let's assume they killed him. It's more merciful. Regardless, once they caught Loki, they tied him up with NARVI'S ENTRAILS and had a snake drip poison onto his face until Raganarok. Sigyn actually stayed with him, trying to bring him comfort when possible despite the fact he was mainly the reason their sons were gone. 

Well, all done with the depressing stuff. 

Love you all and adios!
