Fenrir

is an original character made for The Seven Deadly Sins: Grand Cross mobile game. He is a Beastman, the adoptive son of Loki and the adoptive brother of Jormungand and Hel.

Appearance
In his human form, Fenrir is a short young boy with dark skin, messy white hair, ears and tail of a wolf and a rather well-built physique for a boy of his age. He also possesses heterochromia, his right eye is red and his left one is blue.

History
When he was still a child, Fenrir's parents died under mysterious circunstances. With no family and no where to go, he found refuge in the forests of Midgard where a tribe of Werewolves sheltered him. He lived happily with them until the war between Xatenburg and Isenstein reached the forest and the whole tribe was killed, leaving Fenrir alone and homeless once again. He eventually met up with the God of Chaos, Loki, who took him as his son.

When the Seven Deadly Sins somehow got transported to Midgard, he arrives to the Boar Hat, where he passed out from the freezing cold. Thankfully, he is nursed back to health, and proceeds to explain everything to the Sins. However, word about him traveling in the Boar Hat gets attention of Sigurd, who demanded Fenrir to be surrendered to him. Fenrir tries on surrendering himself to keep his new friends safe, but Meliodas points out they would still be attacked by Sigurd even if Fenrir handed himself over.

Later on, he helps Ban to look for an antidote to dispell Sigurd's curse on Meliodas.

Fenrir later meets his adoptive sister, Jormungand, who joins with him on his quest to find Loki. Together, they help King out against Freyja, after they were transported to Alfheim by Oslo.

Abilities and Equipment
Not much is known about Fenrir's powers, but being a Beastman, he is capable to switch between a human form and a bestial form. Fenrir is shown to handle a couple of a guards, indicating he has some decent strength.

Actually, most of his strength and power was suppressed in order to protect him. After unlocking some of that supressed power, it allowed him to go toe to toe with his enemies such as the God of War Tyr.
