In the United States, this episode premiered as a bonus feature on one of the show DVDs, "Volume 5: Secret Invasion". Disney XD did not air it on TV until almost six months after they aired the official series finale.
Thor's unpowered state combines two secret identities that he used in the comics. Physically, he resembles Sigurd Jarlson, an construction worker identity that he adopted to move among humans. His powerless state and his cane hark back to his original identity of Dr. Donald Blake.
