The second brother hatched and dealing with a classic middle-child syndrome, Dewey is always looking for ways to stand out from the crowd. Dubbed "The Guts," Dewey is quick to throw himself into dangerous situations without thinking, just to prove himself. Deep down he's worried that he's just an ordinary duck so he's constantly itching to make a name for himself. According to Webby, Dewey is ‘sweet and sensitive and full of secrets’.
Dewey is the daring, attention-seeking adventurer of the trio. He loves to explore and do bold and exciting things to stand out, get noticed and have fun. Dewey can be impulsive; he can't sit still too long before jumping into action, often without thinking it through. Dewey desires to stand out as his own individual among his brothers, by trying to impress all those around him by doing big extraordinary things.
Dewey is shown to be compassionate, which shows when he stands up for Webby when everyone was hesitant in "Daytrip of Doom!" He offered to save Mark Beaks even after learning he was a fraud. Dewey can be sensitive; he is easily insulted as seen in "The Infernal Internship of Mark Beaks!" when Huey admits to thinking of Dewey as irresponsible and not serious enough to be successful. This shows that Dewey is also a bit insecure. Dewey is also very emotionally attached to his mission to learn about his long-lost mother, Della. to a point that he wants to learn more about her but is afraid of what the answers may be as shown in "The Spear of Selene!". Dewey is so eager to know what happens to his mother that he is willing to risk his own life just to know the truth of his mother he never knew, as shown in "The Last Crash of the Sunchaser!".
In "The Secret(s) of Castle McDuck!", Dewey claims that his brothers will be hurt if they find out about their mother, similar to he was, though his brothers believe he just wanted to feel special. Confronted, Dewey realizes he has been wrong for doing this.
With his ambitious and quick-thinking personality, Dewey wants to prove himself. And sees himself becoming big like his Great-Uncle Scrooge, he is eager to show his skills in their adventures. Dewey tends to remind Donald and Scrooge of his mother.
Dewey is a small preteen duck who wears a light blue long-sleeved shirt underneath a blue t-shirt and generally styles his hair to stick upward.
The official merchandise for Dewey includes Figurines, T-shirts, Plushies, and action figures. Most of the official merchandise has been released after the 2017 reboot of the show. A full list of all the current official Dewey merchandise is available here.
