The first photo is out of Jaimie Alexander reprising her "Thor" character Lady Sif in an upcoming episode of "Marvel's Agents of SHIELD".
Titled "Yes Men," the 15th episode of the season sees Sif, ordered to Earth by Odin, to find her arch-enemy Lorelei and bring her back to Asgard.
Co-showrunner Jed Whedon tells Zap2It: "It throws our agents for a loop when they find themselves in a fight right alongside this powerful woman from Thor's world." The language barrier also leads to some comedic gags.
The episode in question airs March 11th.
