As we get deeper in to Chapter 2: Season 4 of Fortnite, we continue to get hints and reveals of new Marvel heroes and things being added to the game. We just recently got the official look at the Daredevil outfit, which you have a chance to earn for free if you can rank in the Daredevil Cup. We have also gotten the Iron Man POI area, and even Blade was introduced to the game as an outfit. As far as leaks go, we have reason to believe that heroes such as, Ghost Rider and Captain Marvel could be on the way!
That leads us to right now, where two new superpowers have been leaked. According to HYPEX, one is called Fire Ball and the other is Fire Jump. Unfortunately, not much else is really known about these, and they don't immediately make it obvious which superhero they will be from. The two that makes the most sense are Ghost Rider and Captain Marvel. Ghost Rider obviously has a flaming skull, but is more likely to whip you with a chain and run you over with his chopper.
If you look to the right side of Daredevil in this image, you'll see the fireball icon of what should be the future superpower added to the game.
On the other hand, there's Captain Marvel, who makes more sense to be throwing fireballs. She can also fly, which while not being added to Fortnite, it works with her doing some kind of Fire Jump in the game. This would be similar to Iron Man's high jump and floating ability.
We'll just have to wait and see which hero is the one that features these powers! Thankfully, we likely won't have to wait long, because it looks like the Fortnite 14.30 patch should be on the way, and we will likely see a new POI of some sort, and maybe even the addition of a new boss that uses these abilities!
