For a notail, O-3's personality can be described as bizarre. He is always optimistic about the events around him and often brings gifts to anyone who can withstand conversing with him. This reward is often a "treat" that he has created "optimal for notail consumption." It's rumored that because animals adore him due to his hand-feeding of them, he thinks that the same will work with notails, who he calls "higher animals."

As O-3 spends much of his free time stalking others as if they were fauna, these rumors are not unfounded. Trail cameras and trackers will be placed to keep records of the movement and health of his subject. He never steals objects and is rather careful to not "disturb the environment" by touching objects unnecessarily. These perplexing actions are not improved after confrontation, especially as the reasoning for this all is "to observe and document the natural world." He insists that all living creatures, including the intelligent, such as the notails, are all animals in this universe, and thus failing to observe them in detail is criminal in nature.
