Throughout his life, Sonic has exhibited a great desire for adventure and excitement, in keeping with his super speed. Thrill-seeking aside, he genuinely cares for the people and things he fights for, which at times has led him to break the rules in order to do what he thinks must be done. His greatest flaw in this area may be that he has developed something of a need for action, which leaves him uneasy in times of peace and often influences his decisions more heavily than any other factor.
