Ness is a minor character. He is a young boy in the 6th grade who can use PSI. In addition he is an excellent baseball player and is very ordinary other than the fact that he is an MVP.
Ness is a very dynamic character. Over the episodes he is shown to become more brave and strong, and his level of skill in fighting becomes surprisingly dangerous later on. He is also very friendly and gentle, and while he may not be a favorite to teachers, he gains a lot of respect from other MVPs or non-MVPs. He is subject to bullies in school, but compared to his best friend, Lucas, he can defend himself without starting a fight. While he is not too talkative, he is a popular sixth grader in the school.
