Broly embodies the immense latent power of the Legendary Super Saiyan, his abilities surging through rage-fueled transformations. Within *Super Dragon Ball Heroes*, he accesses multiple forms: his base state, Super Saiyan, Legendary Super Saiyan (distinguished by green hair), and Super Saiyan 3. The game introduces exclusive transformations including Great Ape, Golden Great Ape, Super Saiyan 4, Super Saiyan 4 Full Power, and Super Full Power Saiyan 4 Limit Breaker, along with a later Demon Enhanced Form. His combat features unique skills such as "Broly's Roar," "Destroyer of All," "Devil Resurrected from the Abyss of Death," and "Hyper God Bird of Destruction." Many abilities trigger enhanced effects against Goku or grant immunity to status impairments like stunning.
Broly features prominently across the game's narrative arcs and sagas, including the Broly Saga, Reborn Broly Saga, Episode Broly, Course of Chaos Saga, and Invasion of Darkness Saga. His role shifts between antagonist, controlled weapon, and participant in multiversal conflicts. Specific missions highlight key transformations: Mission 7 (Legendary Super Saiyan), Mission 9 (Great Ape), Mission 11 (King of Destruction), Mission 13 (Super Saiyan 4), and later missions showcasing Super Full Power Saiyan 4 Limit Breaker and the Demon Enhanced Form.
Integrated into the game's multiverse framework, Broly engages in non-canonical interactions and power-ups. Cards depict his various forms, while storylines parallel or reimagine events from his films, including clashes with Goku and Vegeta that lead to fusion (Gogeta). His relationships with Paragus, Cheelai, and Lemo continue to influence certain missions. *Super Dragon Ball Heroes* consolidates Broly's history, abilities, and transformations from his classic *Dragon Ball Z* films and the newer *Dragon Ball Super* canon, expanding them through original game-exclusive forms and narratives.
