Logan is shown to be very timid, and not very fond of risk taking. He's quite socially awkward and doesn't know how to stand up for himself, which led to him being manipulated by and then bullied by Barron. However, after realizing that the phantoms were much scarier, he later builds up the courage to confront Barron. Logan enjoys astronomy a lot.
