Jack Osbourne and his daughter Pearl are honoring Ozzy Osbourne in the most metal way possible … by dressing up in terrifying costumes and scaring theme park guests in his Halloween Horror Nights house.

The dad-daughter pair decided to transform into the scareactors who are responsible for terrifying guests at Universal Studios Hollywood’s Halloween Horror Nights on Thursday night.

This year … the iconic rock legend Ozzy is honored with his very own house — “Ozzy Osbourne: Prince of Darkness.”

In the video … Jack and Pearl transformed into a pair of monstrous bloody bat-priest hybrids.

With full makeup, spooky costumes, and a very apropos bat mask — Ozzy famously bit the head off a bat at a concert in 1982 — Jack and Pearl got ready backstage before making their HHN debut.

When Jack told Pearl she “looked terrifying” in the clip … he meant it!

Before long, the Osbournes were scaring theme park attendees in a room filled with skulls and a massive bat behind them … and doing a great job!
