Constantine is the world's "Number One" criminal and a doppelgänger of Kermit the Frog. He is the main antagonist in the film Muppets Most Wanted, along with his sidekick Dominic Badguy (aka "Number Two"). Constantine sets out to steal an enormous diamond. However, mayhem ensues when he gets entangled with the Muppet troupe on their European tour. He is almost identical to Kermit aside from a few details. His pupils are shaped like Kermit's, but are slanted in toward each other at a sharper angle. Kermit's signature 11-point collar is duplicated, but Constantine's is notably shorter. The most distinguishable difference is a beauty mark on Constantine's face that he has covered up. Kermit is seen with the beauty mark while detained in a Russian gulag, presumably mistaken for Constantine. Constantine also has a strong Russian accent, which he disguised by saying that "Kermit" had a cold.
Constantine belongs to the Jim Henson Company/the Walt Disney Company.
