The second trailer for "Avengers: Age of Ultron" was released on Monday, Jan. 12, bringing with it action-packed scenes, including the much-talked about fight between Hulk and Iron Man in his Hulkbuster suit. Likewise, it also brought in new faces, including the mysterious black woman inside the cave. According to a report, the woman presents a likeness to another Marvel character, Death.

The identity of the cloaked woman seen in the trailer is still unknown. Numerous character names have already been pooled in from various reports. Movieweb supposed the black woman inside the cave could either be Moondragon, Hela, Shuri, Enchantress, Wakandan Dora Milaje or Death. Slashfilm claimed it could also either be X-Men's Storm and Nebula from "Guardians of the Galaxy." However, Death has reportedly already been alluded to in previous films from Marvel.

Death was mentioned in the post-credit scene for "The Avengers." From the video below, Thanos is seen smiling after being told that "to challenge them (humans) is to court Death." Likewise, some viewers were quick to speculate that Thor (Chris Hemsworth) was in the same cave as the woman. This was supposedly shown in the first "Avengers: Age of Ultron" trailer (see video below at the 1:34 time mark).

It's still uncertain if Thor was really in a cave or if he was with the woman. But according to Movieweb, some viewers thought it was Death inside. She and Thor reportedly get into a battle that resulted in the hero's demise, which, according to Slashfilm, is but a hallucination created by Scarlet Witch.

In the Marvel comics, Death doesn't hold a true physical form since she is a fundamental force. However, she can supposedly transform herself into other forms in order to interact with other physical entities. According to the comics, Death can even present herself in the form of a person's loved one. At one point, when Captain Marvel died, she reportedly appeared as his greatest love, Una. Otherwise, the character usually presents herself as a young woman in a dark hooded robe, much like the mysterious black woman seen in the second "Avengers: Age of Ultron" trailer. In the comics she is called Mistress Death whom Thanos fell in love with and wooed with souls as presents.
