How fid balder gp from thr favorite and beloved one in norse mythology. To being just that dude who keeps saying hes Thor's brother but thors like "no ur not" xD
It's so ironic indeed, because Balder is "beloved by all" and practically the Gary Stu of Norse Mythology (it's also why I don't care for his original mythological counterpart, sorry guys).
And it's so strange that technically, Loki got the short end of the stick from Marvel (being portrayed as a ghoulish villain that always fails for decades), but even that Marvelization and demonization gave Loki the most interesting dynamic with Thor, the Norse figure Marvel decided to make the protagonist (I personally consider Marvel's Thor to be a mix of myth!Balder and myth!Thor because in comics written prior to 2010, Thor's very Gary Stu-ish). Balder in the comics is a less hot-headed and weaker version of Thor with a yandere sorceress, Karnilla, obsessed with him.
I think Loki will always or usually end up being an interesting character due to their ambiguous nature in the myths and the large role they play in the mythology, no matter how much different he is in the depiction (Marvel's Loki, to me started out as a mix of myth!Loki, the Devil of Abrahamic religions, and myth!Odin because myth!Loki's magic was just shapeshifting themself and others).
It's a question of whether demonization is better than being overlooked and forgotten.
