Mac is a minor character in Powerpuff Girls Doujinshi.
- Origin: Foster's Home for Imaginary Friends
- Gender: Male
- Status: Alive
He only made one appearance when he was doing things in his locker. He also appeared in character art as a "New Hero Pick" along with Bloo so he is confirmed to have a bigger role in the story.
A bright, creative, and somewhat shy 8-year-old boy and the creator of Bloo who visits Fosters. He almost always seems to know what to do if there is a problem. Mac is generally good-hearted, intelligent and well-meaning and is often the voice of reason among his friends (especially Bloo) when they are about to make a decision. However, his good nature tends to make him somewhat naive.
