Avengers: Endgame - 10 Biggest UNANSWERED Questions We Still Have

5. How Did Thanos Come To The Future Without Any Equipment?

Three things are needed for Endgame time-travel: Stark and Banner's combined machine, a Quantum Realm suit made of nanotech, and a wrist-mounted GPS-style device, to locate you in physical space and time.

All of these are shown working as expected or get described as such across the movie, and yet, when it comes time for Nebula to bring Thanos and his armies forward from 2014 to 2019, she just... does it.

2014-Thanos isn't remotely equipped for time travel, but the scene plays out regardless, with Evil Nebula pressing a number of buttons on a keypad, seemingly 'locking his location in', only to bring the entire Sanctuary II ship through the wormhole and up into space.

The process is so bizarrely silent, in fact, that the other Avengers don't realise Thanos and co. are in the skies, until after Bruce's snap, when all the missiles hit the base.

All-around, a scene made more for the sake of a final fight, than logistical consistency, unless I'm missing something.
