Who is Hydra in The Masked Singer US? The three-headed costume has been revealed, so which celebrities are underneath?

Hydra turned heads during The Masked Singer US season 7 competition because the costume is very different from what we're used to. Instead of having one head, Hydra has three, leading people to believe there's actually a trio of celebrities hidden underneath the elaborate design.

The mysterious serpent was part of Team Bad, joining the likes of Cyclops, Ram, Jack in the Box and Queen Cobra in this villain-inspired team. But who will come out on top?

Here's what we know about Hydra so far...

Who is Hydra in The Masked Singer US?

Hydra was revealed to be Penn Jillette and Teller, the famous pair of Las Vegas magicians. Tricking many with Hydra's three heads (leading to a popular theory of the Three Amigos Chevy Chase, Martin Short and Steve Martin being under the mask), it was actually Teller, who is known for being mute during performances, who provided two of the three voices for Hydra, one of which was apparently based on My Fair Lady's Rex Harrison.

Final guesses from the panelists saw Ken Jeong predict it was Will Arnett and Zack Galiafianakis; Jenny McCarthy had Sesame Street's Bert & Ernie; Nicole Scherzinger ventured Hydra was Will Ferrell and John C. Reilly; and Robin Thicke though they were South Park creators Trey Parker and Matt Stone. However, guest panelist Nicole Byer hit the nail on the head, successfully guessing it was Penn & Teller.

Hydra opened up its stint on The Masked Singer with a performance of "Hey Soul Sister" by Train. Very early we hear three different voices, so either there is a trio under the Hydra mask or it's a very talented voice actor. Take a look:

Hydra's second (and final performance) was of "Sharped Dress" by ZZ Top:

The first series of clues that we got for Hydra in its "cluemercial" were a drawing of a shark, "Triple Head Gum," a pair of skis with "Miami" written on them, a bull on a beach ball, a magic "3" ball with the answer "Ask your amigos," and ATM.

In Hydra's second appearance, the mega clue given to the panelists was a deck of cards, to which Hydra reacted, "How very curious. A deck of cards that's all jokers."

Hydra's costume seems very large, with three heads and three wide legs it could be very possible that there's actually a trio of celebrities hidden within. Or perhaps this is a red herring and it's actually just one person nestled in the middle?

Everything pointed to Hydra actually being multiple people, though most fans were a bit confused on just how many were under the mask. Week one guesses for Hydra had Ken Jeong thinking it could be the Three Amigos themselves, Chevy Chase, Steve Martin and Martin Short, which Robin echoed. Jenny McCarthy threw out Jeff Bridges, Steve Buscemi and John Goodman, the famous trio from The Big Lebowski.

The Masked Singer fans weighed in with some of their early guesses as well. The Three Amigos angle definitely has support, but others think Hydra could be the duo of Penn & Teller, Jack Black or the This Is Spinal Tap trio of Michael McKean, Christopher Guest and Harry Shearer.

With how the performance was played, it definitely had a lot of comedic elements to it, so we definitely like the Chase, Martin and Short guess, but also think Jack Black, who loves to do different voices, is an intriguing option. 

The Masked Singer US season 7 airs on Fox every Wednesday at 8 pm ET/PT.
