His name was Dargo, actually. He took up Mjolnir in some alternate future. Never really gave a s*** about him, to be honest, so whatevs. The Farscape character was a much better dude named Dargo, as far as I'm concerned.
Sif's hair is brunette because the comics included the myth about Loki cutting off her hair but basically just made her new hair black for no real reason (probably because Kirby drew her that way initially and later writers just had to roll with it). She was naturally blond but Loki cut her hair off and the dwarves forged her new hair made of midnight or something flowery like that. Loki ended up hating it because Thor found Sif even lovelier with her exotic new black hair.
Sif is awesome incarnate. I'd really love to see her and Thor portrayed kind of like Johns is portraying Mera and Aquaman now. Badass warrior couple. Fraction's got them f***ing, at least, so that's a start. Oh, and I'd also like someone to remember that she has the innate power to teleport. That was cool. It's a real shame that the only Asgardian anyone remembers has innate divine powers is Thor. Sif's supposed to be able to teleport, Balder's supposed to be able to generate heat and light, one of the gods I can't remember at the moment is supposed to have super-speed, and there are some others with powers.
Zarrko is cool, but whoever called him a second-rate Kang pretty much got it right. There's no reason Kang couldn't be used in Zarrko's place in practically every one of Zarrko's appearances. Still, I like time travelers in general, so I'm cool with Zarrko. As Nubsatopia mentioned, Jurgens used Zarrko to excellent effect as an anti-hero in the King Thor Saga; being from the future, he knew the horrors Thor's reign would bring about for the human race, so he kept showing up in the lead-up to Thor losing his humanity trying to stop him. Looked like his typical villainous attacks, but he was actually trying desperately to save all of humanity, from his perspective.
