Just like all the other hero skins in the Fortnite Chapter 2 Season 4 Battle Pass, Tony Stark has some Awakening Challenges that you will need to complete to get access to his built-in emote. This emote will change him from every day from Tony Stark into Iron Man, and it looks fantastic.
To unlock Tony Stark, you will need to hit level 93 on the Battle Pass, and you will get access to his Awakening Challenges at Level 100. There are three challenges, and one of them is to his emote at Stark Workshop.
You can find Stark Workshop near the Authority. Nestled away in a red barn to the east of the now-abandoned Authority, you can find the workshop where Tony Stark has clearly been tinkering away with some form of advanced technology. All you need to do is make your way there, hit the emote button, and you will transform into Iron Man. You can use this emote in your games to switch between the Tony Stark skin and the Iron Man skin.
All the heroes in the game this season have similar Awakening Challenges that will unlock a built-in emote that performs some for of special function. It is a very nice touch and adds a lot of character to the new skins for the season-long Marvel and Fortnite collaboration. You will normally get access to the Awakening Challenges for each skin just a few levels after unlocking them.
Even though the Stark Awakening Challenges are on the last tier on the Battle Pass, there is more to be done. There are secret Silver, Gold, and Holo Foil skins that you can unlock after you finish the main Battle Pass.
