The cops were playing real-life “Pokémon Go” with King Harris this weekend, it seems … he was arrested during a traffic stop in Georgia — while wearing a Pikachu onesie.

A rep for the Gwinnett County Police Department tells TMZ … cops clocked King doing 60 in a 45 around 1 AM Sunday and pulled him over. The cops say they noticed a firearm near the rapper and ordered him out of the car, but he refused … so the officer arrested him. They also tell us an officer spotted a vape pen with 10 milligrams of THC inside.

According to docs obtained by TMZ … T.I. and Tiny‘s son were booked on a felony charge for possession of a controlled substance, a misdemeanor charge of willful obstruction of law enforcement officers, and hit with two traffic citations for a seatbelt violation and speeding.

King documented his legal trouble on his Instagram stories, sharing a selfie in the Pikachu suit after getting pulled over.

The rapper also apparently posted a pic of his arrest and was cracking jokes about his anime outfit.

He wrote … “Welp guess you can say they caught da Pikachu wit a master ball.”

King shared another selfie — this time sans the Pikachu costume — of himself flipping off the camera.

And he had a NSFW message for the cops … writing “F*** dat police” and saying he was going to have sex with the officer’s wife.

This isn’t the first time King has had trouble with the law … he was also arrested back in 2024 after he allegedly nearly hit a cop car while leaving a gas station. When the officer pulled King over — he said he smelled weed in the car — and learned King had a warrant out from Pickens County for failure to appear in court.
