Alia is a very dutiful character. She tries to set her personal feelings and concerns aside (especially during the Nightmare Incident) to carry out her work for the sake of everyone. She cares deeply for the members of her team and does her best to guide them through their missions without them being harmed. Alia rarely shows any weaknesses, but the Nightmare Incident revealed a deeper, more emotional part of her personality, where she blames herself for Gate's reasons for becoming a Maverick and trying to wipe out all low-level Reploids to create a new nation under his ideal. Due to her past emotional confrontations and her scientific nature, Alia is a realist, claiming she does not believe in "miracles."

As a former Researcher, Alia is highly intelligent, possessing both advanced engineering and analytical skills. She is able to compile and construct new Armors when in possession of the necessary data provided by Dr. Light holograms, and has even managed to reconstruct damaged armors, although to date none of her reconstructions have ever been 100% complete.
