The Egoist is just what it sounds; a person who is more concerned with themselves rather than others. This is nothing strange as it belongs to human behaviour. But like a child, they can go overboard with it, wanting attention and the full concentration of others, or some possession or another. They can often become jealous if they see someone who has obtained a thing they want.
However, not all is bad with the Egoist. Just like any other person, they have positive traits. Usually Egoists blend well with people and get along with them too. And just because they are Egoists, it doesn't mean they can't like or value others. They are far from incapable of caring (unless they have reached too deep in being a Egoist). The reason they value themselves more could origin from various reasons. Perhaps they were spoiled as children, or the opposite. Have they had no one to care for them, they automatically learn to put themselves first, since no one else will. These types of Egoists however are not as prone as the first mentioned category to seek attention. Both types though can be manipulative to get what they want, having learned to push certain buttons to be able to gain their wishes.
Sometimes Egoists lose their touch of their surrounding environment, being too caught up with themselves. Sympathy is not their forte, but they are not heartless. A bit thin on emotions to most, those who doesn't matter to them that is, but to close ones they try harder when they remember to.
It is possible that they grow oblivious to other people's feelings as their main concern is themselves. Sometimes, humans just confuse them. They may also grow bored with those around them, wanting something new. Their own life pattern is however not something that they find wrong, being satisfied with themselves and the way they live. And just because they have themselves as main priority, it does not mean they find themselves to be worth more than everyone else. Many Egoists have low self-esteem, hiding it by acting the way they do. They feel that if others could, they would walk all over them too if given the chance. So therefore, in a way, they protect themselves.

Explanation: Unlike everyone else you can change your body materia and transform into anything (e.g. an animal). This can be used in good purposes for infiltrating evil headcuarters or adjust your physical abilities by transforming and therefor do better in battle. If turned to the evil side, a transfomer could manipulate the "good guys" by looking like their loved ones and break them down.
As a person you are dissapointed with life. You have not so many interests anymore and has become depressed. Of course you can be happy, but your happiness subsides quickly and don't last very long. You isloate yourself from people since you think they would only hurt you, but some part just wants someone equal who understands the pain. When you transform it gives you freedom and you can be anything but yourself. You often pity yourself but don't let people come near and know what's going on with you. But the thought of opening up and risking being betrayed is too strong and intimidating to even try.
Negative aspects: You carry much hate to the world and yourself and in the long run this could lead to dangerous thoughts (suicide/cutting/killing) though the last one is least likeable since you would probably just have too much guilt.
