Alden Bitterroot is the witch/warlock-paranoid supposed ancestor of Denzel Crocker. During the year 1665, when Dimmsdale was still nameless, it was nearly named "Bitterburg" after him. He is also a minor villain of The Amazing Adventures of Sally and Stan.
Alden Bitterroot is interpreted to be a muscular hero in the twenty first century by A.J., but in reality he looked and acted exactly like Mr. Crocker: hunched back, ears on neck, and ranting about mystical beings (in Alden's case, witches instead of fairies), only unlike his 20th century counterpart, the townspeople actually believed Alden. He made large amounts of money by scamming the town into thinking he was really hunting witches, and coerced people into buying his worthless products because if they didn't, "They're a witch!". The townspeople loved him so much that they wanted to name the town "Bitterburg" after him.
He looks very similar to Denzel Crocker in physical appearance, right down to the ear on the neck. He wears black-colored pilgrim styled clothes. When it became known that he was a witch, his flat Pilgrim hat changed to a witch's hat. When he came out of the well after being squashed by Dale Dimm and thown in there centuries later, he is shown to have white hair and a beard.
Alden speaks and acts exactly just like Denzel Crocker, only he is pretending to hunt witches, even though he himself is an actual witch/warlock. Although he usually screams the word "witch" in a similar manner to "fairy godparents", he does not go through the same spasms that Mr. Crocker goes through.
