Nicodemus is a brilliant chemist. One day, however, he accidentally ingested the rare chemical known as "phlebotinum" and was transformed into a large, tentacled eyeball. His speech impediment, however, was a pre-existing condition.
Nicodemus communicates solely in the form of grunts and shrugs. He also has a habit of staring and shuffling. However, he loves his wife dearly, and will attack anyone who threatens her with all the wrath an eyeball can muster.
Apparently, he's quite the comedian.
