Fritz is an awkward, clumsy boy in the community. He is known for his minor careless mistakes, "But each such error reflects negatively on his parents' guidance and infringes on the community's sense of order and success." Because of this, he is most likely an outcast. It is unknown what happens to him.
In The Giver, when he receives his bicycle as a Nine, Fritz immediately bumps into the podium. This causes Jonas and his family to wince, thinking about how his bike will be left carelessly outside.
