The teen who shot up an Indianapolis FedEx facility and killed eight people was reportedly part of a bizarre Internet subculture obsessed with "My Little Pony."

Posts on Brandon Hole’s since-taken-down Facebook page appear to indicate he was a member of the "Bronies" community — a group of mostly adult men who are extreme fans of the kiddie toys and animated television show, the Wall Street Journal reported.

INDIANAPOLIS FEDEX FACILITY SHOOTING LEAVES 8 DEAD, GUNMAN ID'D

Some members are sexually attracted to the characters, while the group also has allegedly displayed far-right tendencies.

"I hope that I can be with Applejack in the afterlife, my life has no meaning without her," Hole wrote on his Facebook page at 10:19 p.m. Thursday, less than an hour before his rampage began, the outlet reported.

The post included a photo of Applejack, a blond pony that is a main character on the show. 

The name Brony is a mashup between "bro" and "pony" — and the group has a history of extremist tendencies, the outlet said, citing an internal Facebook memo they reviewed that detailed the post. 

"Brony online culture has displayed elements of far-right and white nationalist extremism," the memo stated.

Facebook stopped short of saying Hole’s pony-love had anything to do with the shooting, writing in the memo there was no clear evidence it motivated the massacre. 

Hole, a former employee of FedEx, opened fire in the facility before turning the gun on himself.
