Jonas (The Giver)

Jonas is the protagonist of Lois Lowry's novel "The Giver". He is a boy of the age of 11 (later 12) who is assigned to be the receiver of memories. He receives these from the titular senior now known as the Giver, who tells him not to reveal them to anyone, not even his family. At first, Jonas is colorblind, but gradually begins to see color. He lives with his parents and 7-year-old sister Lily.

A heroic side is when, upon finding out what a "release" is (meaning that his father makes a baby comfy only to inject him to death), he decides to save the infant "newchild" Gabe by sharing his memories with the latter.
