Strengths:
Empathy - His kindness and compassion for others is derived from his innate form of Empathy. As odd as it sounds, while he has a affinity for these he can not use them consciously and is subject to getting a feeling for what someone is planning and knowing what someone is feeling. The problem is this only works on surface emotions without training and anyone who is good at hiding or even altering the flow of emotions can stop him in his tracks without sufficient training. So while he is at the moment weakened by his empathy, training could turn it into a great strength.
Nimble and Quick - What he obviously lacks in strength, he makes up greatly in having a someone unnaturally nimble body. In due to his normal focus on Exercise and training, he has found that he can move quickly and efficiently due to both his own natural movements and his lightness. As such and due to his bodily structure, he is light and quick on his feet, making him able to react much faster than someone twice his size even without the need of the force.
Noble Blood, Controlled Mind - Due to his place in society, Alexander has been brought up to hold his tongue and clear his mind. This helps him avoid rash actions and focused on the topic at hand while trying to talk the man down, and even if that fails allows him to keep a cool head in the following fight. His place also gives him a small amount of authority and wealth, though nothing like that of someone in a upper government position thus keeping him in a low upper class place.
Kind/Caring - If there is one thing that Alexander prides himself on, it is his kind and caring nature that sometimes gets the better of him. For the most part though this is a strength as it forms bonds that would otherwise have not been achieved by alternative means. He is ready to show mercy whenever possible and as such makes him highly against the unwarranted cruel treatment that people are shown by elitists.
