Cumulus

Professor Cumulus
is a behavioral specialist who reviewed Commander Julius Root's iris-cam video of the meeting with Artemis Fowl II during the Siege of Fowl Manor.

He debated with Dr. Jerbal Argon during Artemis Fowl, as to whether Artemis was lying or not. At first, he hated Argon, but then they began to become friends. He and Argon found Artemis Fowl's "mistake", allowing the fairies to enter and collect their gold after Fowl was dead. Interestingly, in The Arctic Incident, Opal Koboi states that her parents are in an asylum, named Cumulus House.
