The First Spinjitzu Master, Wu and Garmadon (Ninjago)

Headwear and hairstyle: His signature accessory is a straw hat that obscures his facial features. Only his long white braided hair, plaited at the back of his head, is visible underneath.
Facial features: He is depicted with narrow eyes and long eyebrows, like his youngest son, Wu. His eyes are golden (amber).
Elemental Garb: He wears a black kimono with white sleeves, and a golden dragon embroidered on the back. This combination of black (the color of the Oni, the destroyer) and white (the color of the Dragons, the creator) clearly demonstrates his essence.
Build: Standing at about 178 cm tall, he had a slender build (about 60 kg), characteristic of an ascetic warrior who spent his life in meditation and training, rather than in feasting.
A strict but loving father: He loves both his sons sincerely. But sometimes he's busy writing scrolls about the various elements.

Clothing: In his early years, he didn't wear black armor. Garmadon's childhood wardrobe was similar to his brother's: he wore a simple shirt (hi), often in darker, muted colors.
Hair and Facial Features: He had brown hair, typically cut in a bowl cut or mickey-style. Garmadon's eyes were black, like their mother, who had been missing for some time.
Personality in appearance: Even as a child, his appearance was sterner and more sullen than his brother's. While Wu was a curious boy with freckles, Garmadon was often depicted with a more furrowed brow.

Hair Color and Style: As a child, Wu had ash-blond hair. Unlike the severely styled hair of his youth or the long, flowing hair of his younger years, young Wu wore his hair short (either a mickey or a bowl cut), which made him appear even more youthful.
Distinguishing feature: The most noticeable detail of his appearance is the freckles on his cheeks. This makes him appear warmer and softer compared to the stern young warrior.
Clothing: As a child, he didn't wear elaborate armor or ifu. His wardrobe consisted of a simple white shirt (hi) with a red lotus symbol, paired with loose sand-colored pants. This emphasized his status as a disciple living in a strict temple.
General impression: Large eyes, snub nose. As a child, he looks less like a warrior and more like an ordinary boy, curious and full of life.

Garmadon and Wu are the sons of the same father who raises them, or in other words, the First Spinjitzu Master, this is their father.

In fact, things are actually quite strong between them, and the First Spinjitzu Master acts like a loving but strict father who cares for his sons as he should. After all, the First Spinjitzu Master claims to love his sons Wu and Garmadon equally. And yet, his sons don't even know their mother, as she's long since disappeared. But the First Spinjitzu Master never speaks of this. He only tries to train his sons in his free time. And in other times, he sometimes writes scrolls about the elements of Ninjago, the world he created.

The world of Ninjago itself is one of the kingdoms. There are 16 of these worlds in total. One of them is the Ninjago World, where Wu, Garmadon, and the First Spinjitzu Master live. There are islands here that aren't included on the world map. But the largest one there is an island shaped like a yin-yang. It is home to many different creatures, including snake-like creatures with a human-like body but a snake-like head and legs, as well as ordinary citizens and those who will wield elemental powers.

The world itself is full of dangers, and one island has its opposite side, like yin and yang: one bright side, where they all live, and the other, submerged in water, is much worse and more dangerous to live in. That's why no one ever goes there.

The Serpentines (those snake-like creatures) have their own separate empire, which includes six clans of this order. Each clan is fierce in its own way. But humans and the Serpentines have made a pact: humans do not trespass on Serpentine territory, and the Serpentines do not disturb humans.
