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 supervillain, 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).

But, that didn’t stop Williamson from staying loyal to his man … with celeb jeweler ZoFrost gifting the young baller his own blinged-out gauntlet, which is fittingly holding a basketball.

The piece is incredibly detailed … and even features all the Infinity Stones!!!

Of course, the Association is resuming its season at the end of the month … and Zion’s Pelicans are gearing up to make a last-minute playoff push.

The league better hope the kid doesn’t snap his fingers in Orlando!!!
