I did not have the chance to read the recent Thunderstrike limited series, but I was told it ends up with Eric's son, Kevin, taking the thunderstrike hammer and you know, being Thunderstrike under the tutelage of Valkyrie.

He's got the Asgardian thing going on.

Does anyone (any one from the site maybe?) have some kind of semi-spoilers for me as to his whereabouts, and/or would ask any Marvel writer why was he not introduced?

If I were to speculate, I'd say it'd be pretty cool to have, you know, Thor girl, Kevin Thunderstrike, this Loki kid, her girlfriend Leah, and other asgardian youngsters making some kind of "young asgardians" (not thor corps please). You know, in the vein of new mutants, young avengers, (there's even a young Enchantress out there) maybe the initiative, and stuff, maybe throw in some Sif and/or Valkyrie, as mentors. That'd be something I'd buy times, nothing wrong with two ongoing conflicting Thor titles, nothing wrong with journey into mystery. 

I went and overdid my question, where are the rest of asgardian related heroes? Red Norvill, Thunderstrike, Beta Ray Bill, etc? 

You heard it first here, on Comic Vine.

i dont know what happened to him, but thats not valkyrie, it's A valkyrie.

Oh. I didn't know that, but now that you mention it, yeah, I remember being told it was even a young girl. 

So you see. "Young Aesirs". I'm pitching ideas here.

Thunderstrike is currently in Fear Itself: Home Front #5-7 teaming up with X-23, Power-Man, Amadeus Cho and Spider-Girl!
