My guess: 4* Void. Possibly 4* Iron Patriot.
They wouldn’t need to have all three powers working for another 3 months.
My hope is that there will not be a season 4.
I agree, I think it will be a new 4* and rewarded similarly to how Fury was released. I know Ice specifically mentioned both Void and Iron Patriot before so I think there is a strong chance its one of them.
Im hoping for iron patriot
Iron patriot will be 4* and a lazy version of IM40, or IM 35 take your pick.
5 star lazy x farce.
I would think they would cycle Fury over again.
I doubt it. They want people to spend HP leveling up covers. The only way to ensure that is to provide people exactly one cover.
Yea, you should start seeing Fury as a top prize in some select PvP events now. Which should infuse some interest in these individual events.
The risk is then very little 
More Fury!
Think like them. It can’t be Fury. People are going to insane lengths to get season score for Fury covers now because they’re exclusive, and as others have already pointed out the moment Season 3 rewards come in the whales will have theirs fully covered faster than you can say Pay2Win.
They need a fresh carrot to dangle and drive this madness for another three months. The just introduced Sentry not all that long ago. Seems a little soon for Void. Iron Patriot is a much safer bet.
We can dare to dream though: 99* Galactus. His powers are Nom!, Nom Nom!, and Om Nom Nom Nom! 
So 2* Fury?
Clearly that will be the forum’s reaction to Season 4. I’d say 50/50 on the actual reward though.
Well played, sir. Well played. 
Iron patriot deserving of a 4* ?? Or would they go with Osborne in a different suit for the 4*? Goblin, Armani?
I am thinking X-man + 4 Star!? Profesor X or Phoenix.
Season 4 will see the introduction of “season tokens” as top prizes, which have the increased chance of obtaining a 4* hero! All of your favorites, like Baglady, Bagverine, and the soon-to-be-nerfed BagFury!
1* Wolverine (Bone claw)
The season 4 prize should be that there are no more seasons. Hands down the worst aspect of this game by a country that being said, it’ll be a new 4* character and fury will be rolled into the wolverine/in is woman rotation. Fact
In a day we’ll see the rewards for the Falcon tournament that closes out Season 3. Thus, we’ll at least know what the first tournament of season 4 will be.
