Speculation has come up on who the alien invaders will be. Who has Loki brought with him to attack Earth? I am NOT entirely certain of anything, but I am sure that these few things caught my eye.
First being the hovercrafts the aliens ride on, people have ideas as to what they look like, but to me those crafts along with what appeared to be a mother ship during this scene here.
I am thinking that it could either be this "Leviathan" We keep hearing about- or it could be- because it resembles in shape and look, that of Annihilation Wave- The Arthrians.
I still believe that Annihilus will be our secondary villain. The army though- paints this odd picture of races, they appear to be Frost Giants, but wear armor that would fit in Thanos' army. I am not completely certain of any of this- as I stated above, but it is my guess, as we all are doing at this point. We can only speculate, so I do- only time will tell us who this army consists of. On May 4th, when The Avengers assemble, we will know. I would also like to hear what you think, who do you have in mind- also keep in mind that this article is strictly on opinion and for a good fun debate.
