Piccolo (Mini) is the childlike version of the Namekian warrior Piccolo who appears in the anime Dragon Ball Daima. In that story, Piccolo is among the heroes transformed into a small, youthful version of himself after a wish is made to Earth's dragon Shenlong as part of a scheme connected to the Demon Realm. Although his body is dramatically reduced in size, his mind, memories, and fighting experience remain fully intact, so he behaves and fights as a mature warrior rather than an actual child. His familiar cape, turban, and stern expression are all scaled down to match his new stature, and he retains the distinctive green skin, pointed ears, and antennae of his people.

Piccolo's background is closely tied to the lore explored in Dragon Ball Daima. He is a Namekian, a race of alien warriors with regenerative abilities and a deep connection to the Dragon Balls, and the series reveals that the Namekians originally come from the Demon Realm. Because of this connection, Piccolo has a personal stake in the journey into that realm, as it holds the history of his people and answers about the source of some of his powers. His role in the story is that of a key combatant and a dependable ally who travels alongside Goku and Vegeta, lending his strength to the battles they face against the demons and other dangers of the Demon Realm.

In terms of personality, Piccolo (Mini) remains the same calm, serious, and composed figure he has always been. He is pragmatic, observant, and highly tactical, often analyzing situations carefully and acting as a voice of reason within the group. The contrast between his small, youthful appearance and his mature, stoic demeanor is one of his defining characteristics in the series. He does not dwell on his reduced size and instead focuses on the mission at hand, showing little outward frustration or concern about the change. His dry wit and blunt honesty also remain part of his character, even in this altered form.

Piccolo's motivations in Dragon Ball Daima center on confronting the conspiracy that caused the heroes' transformation and uncovering the mysteries of the Demon Realm, especially the truth about the Namekian race and its origins. He is also driven by loyalty to his comrades. While his long and well-known bond with his former student Gohan is part of his broader history, in this story his key relationships are with Goku and Vegeta, with whom he works closely as an equal partner in battle. Their dynamic highlights Piccolo's role as a trusted and capable member of the team rather than a mentor figure.

The series gives Piccolo meaningful development by tying him more deeply to the Demon Realm and expanding the mythology of the Namekian people. Despite being physically de-aged, he is portrayed as wise and experienced, and the story emphasizes that his power and potential are not diminished by his smaller form. One notable focus of his development is the origin of his ability to grow to an enormous size. In Daima, the heroes visit a giant-sized world within the Demon Realm, and the series suggests that the Namekians learned this giant technique by observing the immense beings who live there, providing an in-story explanation for a power Piccolo has long possessed and sometimes overlooked.

As for abilities, Piccolo (Mini) retains the full range of Namekian powers. He has superhuman strength, speed, and durability, can stretch his arms to strike from a distance, and can regenerate lost limbs as long as his head remains intact. He is also able to sense and control energy, known as ki. His signature attack is the Special Beam Cannon, a powerful piercing energy beam that he charges at his fingertips before firing. In addition, he can use the Super Large Body Technique to greatly increase his size, a skill whose origins are addressed during the events of the series. Even in miniature form, Piccolo remains a formidable fighter whose abilities allow him to stand alongside the strongest warriors in his group.
