Much in the same way you don’t give a mogwai food after midnight, you apparently also don’t give the Fishstick skin in Fortnite any power as they became an entirely different, completely terrifying entity.
This comes from the trailer for the Fortnite x Avengers Endgame LTM, which you can check out for yourself below.
Drop in with your squad, search for the Avenger’s items and take the fight to Thanos! Can you eliminate Thanos and his army before the last Infinity Stone is found? Or will he complete the Infinity Gauntlet and pick up a Snap Royale? Play the Marvel Studios Avengers: Endgame LTM now!
There’s no end-date in sight, but the Infinity Gauntlet event previously went for a long old while before it was taken out. Presumably this LTM will also go the distance, maybe for most of Endgame’s theatrical run, or at least for its “peak” weeks. It’s set to smash a million and one records, so get used to seeing Avengers in Fortnite for the foreseeable future.
