Aviva is a strong leader and an active member of the crew. However, she can take competitions a little too seriously, and can oftentimes be quite stubborn. While she has been shown to be somewhat arrogant in her abilities (no doubt due to her intelligence), she does care about the well being of her crew and the animals they encounter, and she does not value her inventions over her crewmates. Although often hard at work, she can sometimes be lazy and feel unmotivated.
