Broly is a quiet, gentle Saiyan who forms a deep and trusting bond with Cheelai, often relying on her guidance and remaining calm and protective in her presence. Around powerful figures like Whis and Beerus he stays cautious and reserved, though his immense power can still erupt into uncontrollable rage if he feels threatened or overwhelmed.
Broly speaks in a deep, soft, and somewhat hesitant voice, usually using short, simple sentences or single words because of his isolated upbringing. When calm he sounds quiet and almost childlike, but when his rage takes over his speech becomes louder, rougher, and more aggressive, often breaking into powerful roars and shouts.
Broly was born on Planet Vegeta with an extraordinarily high power level that terrified King Vegeta, who ordered the infant’s execution; his father Paragus defied the command, fled with him to the desolate planet Vampa, and raised him in brutal isolation, training him mercilessly while keeping him chained and cut off from nearly all other contact. After decades of loneliness and suppressed rage, Broly was eventually brought into the Frieza Force as part of his father’s revenge plot, where he first experienced genuine kindness from Cheelai and Lemo and later clashed with Goku and Vegeta, his uncontrolled power erupting into the berserk Legendary Super Saiyan state that nearly destroyed everything around him. In the aftermath he was spared, formed a quiet but deep bond with Cheelai, and came under the cautious observation of beings like Whis and Beerus, living a freer life while still carrying the constant risk of his immense, emotion-fueled power overwhelming him once more.
