For update 15.21, 90s pop icon the Predator is appearing in the game and will be joined by another character next week. Rumors suggest it will be Lara Croft or Terminator as they fit in the update 15.21 hunter theme. Here is the guide for you to hunt down the Predator and as a reward, you can use its skin with the invisibility tech.
Today, January 20, 2021, Predator arrives in Fortnite. The Alien Hunter is available to unlock for current battle pass holders as a new challenge. The Predator is a powerful roaming boss that can be found and fought on the map. It can be found stalking the Stealthy Stronghold.
Kill the Predator and you will be rewarded with the Predator's Cloaking Device. This will allow you to become invisible for a short time. This might be imbalanced at a first glance, but remember you have to successfully kill the Predator, a powerful boss, and all the other players hunting it. Besides, the item has a balancing check as equipping a weapon or dipping in water will remove the invisibility. There is also a 30-second cooldown before you can use the invisibility again, and it does refresh when you decloak.
The Predator skin also comes with an emote called "Bio-Helmet Online." The Predator takes off his helmet and lets out a primal scream, just like in the movies.
