Star level is a game mechanic for characters in Bloons Adventure Time TD. By spending character resources, the player can increase the level of characters to unlock permanent enhancements, access to more upgrades, and additional trinket and ally slots. All characters start at star level 1 and can level up to star level 10, with the cost increasing as they gain levels.

Star level bonuses

• Levels 2, 4, 6, 8, and 9 unlock a permanent bonus for one of the character's stats.
• Levels 3, 5, and 7 unlock a new upgrade (or two upgrades in the case of Hunter Marceline at level 3).
• Levels 2, 4, 6, 8, 9, and 10 unlock a trinket slot.
• Levels 3, 5, and 10 unlock an ally slot.
• Level 10 unlocks a bonus unique to that character.
