Hakka is a tall, fit man with a lean and taut build. He is often seen wearing a mask and having a tree-like left arm. He is agile, dexterous, flexible, and strong, important physical traits that allow him to explore and live in the forest he protects. He may look young, but in truth, he has lived multiple human lifetimes thanks to the forest's magic which give him wisdom beyond his years, and although he lived in the forest throughout his life, he is always open towards other ways of living.
