Loki I know for sure is some mischievous little dude who bothers his fellow Norse gods from time to time. Baba (taking a wild guess here!) is probably some "father" god. ...I'm just going loosely from knowing the Chinese word for father being baba. Probably not right, but I don't care!

Loki, god of fire. I believe he represents the negative aspect, while Heimdall represented the good kind that heats houses. Also trickster god & of thieves,gamblers.
He is the kid of Laufrey & Farbuti,fire giants,so he's not technically a god. Just a sworn brother of Odin. His kids with Angrboda are Hel,Jormungard,and Frenir.

He loved to go adventuring with Thor & Odin. He often got the gods into situations and the panthenon amused themselves watching how he got them out of it.
His worst crime was tricking his blind brother Hod into killing Baldur. Then he prevented Bladur from being ressurected by taking on the form of a giantess & refusing to cry.
