NY Giants star Xavier McKinney plays on the gridiron like a comic book villain ... and now, after getting a huge torso tattoo, his stomach art matches his game!!
The 24-year-old safety recently hit up LeBron James' ink artist, Ganga, for the piece ... and it turned out awesome.
His abs are now covered by an image of a pissed-off Thanos ruling over a smoldering city. On one of his obliques, meanwhile, he got a pic of the Joker put down -- and on the other, Ganga drew on "Guardians of the Galaxy" character Groot.
Ganga also touched up some of McKinney's other tats that he had gotten previously ... while adding the words, "Most Wanted" and "Beware of Dog" as well.
The NFL player was clearly thrilled with the final results ... sharing pics of his new ink while writing in a caption, "Tattoos over war wounds .."
"Special thanks to my brother @gangatattoo and all the artist who helped bring this piece to life."
McKinney will have to wait a couple days to show it all off on an NFL field -- the Giants don't play until Monday night against the Packers -- but if McKinney snaps (get it?!) then, don't be surprised!!!
