Anime & Manga
- The Blob from X-Men. A rare example of a dramatic version of this trope.
- Augustus Gloop from Charlie and the Chocolate Factory - the narrative outright berates him over this.
- Piggy from Lord of the Flies is an intellectual, with poor eyesight, a weight problem, and asthma. He is the most physically vulnerable of all the boys. Despite his voice of reason, he lacks leadership qualities so his advise ends up being completely ignored.
- Rowley Jefferson from the Diary of a Wimpy Kid series generally fills this role. The fact that Greg Heffley is more-or-less stuck with him as a best friend is a constant indicator of Greg's unpopularity.
- Harry Potter's Neville Longbottom starts this way. He sure doesn't end that way.
