Branch is a Troll with bluish skin and deep navy hair. He has a calmer, darker color palette compared to other Trolls, with hair that extends straight upward. He wears a black vest and green shorts. His face is round with large eyes that clearly show his emotions, though he rarely smiles and often wears a blank or frowning expression. His thick eyebrows and half-closed eyes give him a cold and indifferent impression. After overcoming past trauma and finding happiness again, his appearance undergoes a change: his dark hair turns a brighter blue, and his face smiles more often, giving off a much warmer and brighter atmosphere. His cautious expression and subdued colors are his defining traits, but his growth is visible as his demeanor brightens over time. On the surface, he is blunt, soft-spoken, and a realist who always prepares for the worst-case scenario. Unlike other Trolls who spend their days happily singing and dancing, Branch spends his time gathering food and building shelters to prepare for danger. He developed this personality due to a painful childhood experience. As a child, he loved singing and had a bright personality, but his location was discovered by a Bergen while he was singing, leading to the loss of his beloved grandmother. Believing this was his fault, he carried deep guilt and gave up singing and dancing entirely, distancing himself from others. Though he seems cold and detached, he is actually a Troll with a heart warmer than anyone else's. When his friends are in danger, he puts their safety before his own and is the first to step up to protect everyone. He is clumsy at expressing emotions but shows his sincerity through his actions, possessing a strong sense of responsibility and self-sacrifice. Branch undergoes a major change after meeting Poppy. At first, he couldn't understand her constant positivity, but through their adventures, they come to understand each other. Thanks to Poppy, he finds the courage to overcome his past wounds and sing again, gradually regaining his bright self.
