Berholt appears in the Opal Deception as an employee at The International Bank in Munich, Germany. He is noted to be terrified of elevators; that being one of many phobias. Kurt, a bulky guard at the bank says, "Everything terrifies him, from spiders to elevators. It's a wonder he even gets out of bed in the morning." It's also noted that even when Artemis Fowl insults him in his snotty teenager persona, his smile never wavers.
