In Brawl Super-Star Legends and its sequel Brawl Super-Star Legends II, players can somewhat customize their characters to personalize gameplay. While players can't actually customize a character's appearance (aside from alternate costumes and color schemes when starting a match), they can customize each character's taunt, introduction screen, and winning screen.
Each character in the game possesses three unlockable taunts, four unlockable introduction screens, and four unlockable winning screens from which to choose. These customization options are unlocked by playing matches, as the player will continue to level up and unlock new items.
In Brawl Super-Star Legends II, players may equip their characters with stat-boosting clothing items. For more information, see the main article: Stat Clothes (BSSL).
