Well, looks like we have to guess and analyze fruitlessly no longer: there’s a new “Axis” teaser out there for you.
Facing off against Green Goblin, Loki, Sabretooth, Red Skull, Doctor Doom and Carnage respectively, these are the heroes chosen to take a stand in Marvel’s next event, written by Rick Remender. Take a look:

As we guessed we have Iron Man, Deadpool and Medusa, as well as the confirmation of Storm and the reveal of Thor and Luke Cage. An eclectic bunch for sure, but Remender writing Deadpool again is certainly something to look forward to.
What’s interesting to note about the image is in the colors. The previous image, with the characters we perceive as villains, used much brighter colors, whereas here our heroes are bathed in the dark. If “Axis” is, presumably — given all the design work — about flipping things upside down, it’s possible that this cast is less heroic than usual.
We’ll let you know more as we find it out.
