Crazy Carl is a minor antagonist turned supporting character in the Sonic the Hedgehog film. He is the first human to discover Sonic and attempts to catch the speedy mischief maker, but his attempts always end in failure. To add insult to injury, nobody in his town takes the old man seriously and starts calling Crazy Carl.
Carl is portrayed by Frank C. Turner.
Crazy Carl has tenacious yet unstable personality in which he attempted to capture Sonic in spite of his repeated failures and later to fight Robotnik with a chainsaw to defend Sonic.
Sonic the Hedgehog
Crazy Carl is first seen having made a drawing of Sonic to prove the hedgehog's existence, but to his frustration, no one in the town takes him seriously.
Unbeknownst to Carl, Sonic is alerted to Carl being onto him. Eventually, Carl decides to take matters into his own hand by laying numerous traps in his bid to catch the speedy hedgehog to prove to the townsfolk, but Sonic thwarts Crazy Carl every time to protect his safety. Carl is vindicated later in the movie when Tom and eventually Maddie, upon actually seeing Sonic, realized that Carl had been right all along.
Carl is later seen again, along with officer Wade Whipple, after Sonic inadvertently returns to Green Hills using a Ring Portal and is injured by Dr. Robotnik. The old man tried to protect Sonic with a chainsaw in front of a police, bravely proving to the townsfolk that Sonic is indeed real. After Robotnik was dealt with, it is presumed that Carl is content having Sonic living in his town.
Sonic the Hedgehog 2: The Official Movie Pre-Quill
Crazy Carl makes a brief appearance in the official prequel comic to the 2022 film Sonic the Hedgehog 2. While Sonic is thinking of a heroic name to call himself, Carl suggests the name "Blue Devil" as he thinks it is the perfect name for him. Sonic responds that his name would still be way better than "Crazy Carl", causing Carl to state that he is not as crazy as he looks.
- The drawing of Sonic Crazy Carl shows in the film is a reference to the "Sanic" internet meme.
