The Masked Singer quarterfinals aired Wednesday night (April 23), and all eyes were on one quirky, big-brained contestant—Mad Scientist Monster. Dressed in a fuzzy lab coat and powered by musical mayhem, this mystery performer has made it all the way to the top five of The Masked Singer season 13.

In true Masked Singer fashion, the clues came flying in every week. From radar guns to sandcastles and Ford Raptors, viewers have been connecting the dots and scratching their heads.

The costumed stars still in the running—Boogie Woogie, Mad Scientist Monster, Nessy, Pearl, and Coral—put on another dramatic performance. But it was Mad Scientist Monster’s rendition of Coldplay’s “The Scientist” that had fans buzzing.

Could a country superstar be hiding under all that monster fuzz?


All eyes on Mad Scientist Monster in The Masked Singer quarterfinals

From the start, Mad Scientist Monster had a clear mission: to entertain, confuse, and maybe sneak a little science into the show. In their first performance, they dropped major hints while holding props like a radar gun marked “Fast,” a martini glass, and even staring into a fish tank.

He said he was once “on track to be the best in [his] field” and wanted to be “reintroduced to fans.” The judges tossed around some big country names—Luke Bryan, Luke Combs, and Blake Shelton.

But that was just the beginning. Week after week, Mad Scientist Monster added new layers to the mystery, leaving fans of The Masked Singer scouring the internet for clues.

With each performance, it became clearer that this wasn’t just a random celebrity. This was someone with serious music cred.


The second clue round brings out cruise ships and boy band energy

The second week of clues had the judges digging deeper. A grandfather clock ticked away while a cruise ship floated past a sandcastle. The monster also revealed a personal tidbit—he first met his wife at a Friendsgiving dinner and reconnected years later.

The biggest bombshell? He claimed to have “won the same award as both Backstreet Boys and BTS.” That detail threw the judges into boy band territory, prompting new guesses like Alan Jackson, Tim McGraw, and Keith Urban.

The judges weren’t the only ones guessing. Viewers at home were now tuned into every word, every item on set, trying to decode what kind of star could claim those connections and accolades.

One thing’s for sure—this is someone who’s been around chart-topping acts, which only adds fuel to the Masked Singer guessing game.


A big 2010s energy and a solo comeback hint drop more clues

By week three, Mad Scientist Monster wasn’t holding back. They declared they “made it really big in the 2010s” and “won every award out there.”

This time, viewers saw sun decorations, a silver pickup truck, and more drama. The monster shared that they went solo after disagreements with their “crew.” Plus, they claimed to have “performed with someone from season four of Masked Singer.”

The panel’s guesses this round? Brad Paisley, Blake Shelton, and Billy Ray Cyrus.

The silver truck, the sun, the solo artist journey—all these things pointed toward someone with a long career and a deep catalog of hits. No surprise that The Masked Singer fans were now locked into the idea that the mystery singer might be a major country artist who dominated in the last decade.


Tennessee pride and Ford trucks deepen the country connection

Week four’s clues brought out even more Southern flair. A Tennessee flag waved proudly in the background, and the performer dropped another vehicle clue: he drives a Ford Raptor.

He also shared that he’s “younger than Ken Jeong,” which knocked a few guesses off the table. And of course, he dropped another music hint—he’s shared the stage with Keith Urban and has “won many awards for singing.”

Panel guesses included Kenny Chesney, Trace Adkins, and Tim McGraw, solidifying the country vibe that’s been building all season long.

At this point, the Masked Singer audience had more than enough to suspect the voice behind the monster mask is someone country-famous. And the Raptor clue didn’t go unnoticed—it sparked a whole thread of new guesses online.


A summer break clue and a party-loving country theory

The fifth and latest round brought even more personal details. A calendar showed “Summer Break” written across August 2025. Then came the biggest reveal yet: the monster said his wife is an orphan.

Knight chess pieces also appeared, and the monster described himself as being “best known as a party anthem kind of guy.” The party-loving clue got fans thinking about country hits that scream summer fun.

This time, the panel threw out names like Gary LeVox, Kane Brown, and Jelly Roll.

Could this be a stealthy return for one of country music’s biggest stars? Either way, The Masked Singer has pulled off one of its most entertaining mysteries yet.


But online, one theory kept growing louder: Garth Brooks.

Not only does he check several of the clue boxes, but fans also spotted that the radar gun from week one looks eerily similar to the one featured in Garth’s “Catch” music video.
