Look out, NBA ... Zion Williamson officially has the Infinity Gauntlet!!!
The rookie phenom is ringing in his 20th birthday by channeling his favorite comic book super-villain, Thanos ... copping the Marvel-themed pendant -- with a minor twist.
Remember, Zion has gone on record saying his fav character is the bad guy from "Avengers: Endgame" ... and even said he wanted Thanos to BEAT Captain America and the gang at the end of the movie.
Spoiler alert -- Thanos didn't win ... he actually dies when Iron Man gets a hold of the gauntlet and snaps his fingers, thus killing himself in the process (RIP).
