both of his parents were (frost)giants also in the norse myth, but he is still the god of fire anyway. It said that Loki was born because his father Farbautis (which means „terrible thug” or „lightening” threw a lightening at his mother Laufey (Laufey is actual his mother, not father like in the marvel stories and her name means something like "leaves" or "irland of trees") so she got Loki...strange way to get a child, but well... I guess because of the lightening in connection with leaves Loki has something to do with fire. Maybe usually a tree starts to burn when a lightning hit them XD Don`t know...
but tha’ts something i don't understand, too. i didn't read the comics, sorry, but wasn't logi the god of fire? and logi and loki are two different giants, they fought in a contest. And isn’t odin lokis blood brother? and wasn't looki "so handsome men and women would fall for him"? but in most fanarts i see he looks so gaunt (nothing against yours, i love them!)
no logi is not a god, he is a firegiant and the personification of fire. So you can say Logi IS the fire.
and yes Loki and Logi fought each other in a contest, which Loki lost, because nothing can "eat" faster than the fire itself.
Loki and Odin are bloodbrothers, because Loki wanted to be adopted by Odin to become one of the Ęsir. And yes Loki is described as very handsome but when it comes to beauty it always depends on your own view I guess and also of the century. I mean the ideal of beauty has changed a lot of times during the centuries anyway.
that`s also in the myth, but original Laufey/nal is his mother, not father.^^ But the wildfire is Logi (a firegiant and the personification of fire itself, while his siblings are personfications of the wind and sea) Loki is just a firegod but unrelated to them. Logi and Loki are often confused with each other.
That is not really right. There is no description in the norse mythology about his or many other gods detailed looking. He is just described as handsome. The idea of the red hair came much later by the influence and interpretation of artists, also in relation with Christendom - red hair = danger, evilness, devil, helfire...But the old norse mythology itself never says clearly something about his haircolor. In some old paintings he has black, red, or red-golden hair. It`s all about interpretation
