Burn, a ruthless operative of the Alien Hunters, relentlessly pursues the Star Drops—celestial fragments from a disintegrating world—which he claims as his exclusive prizes. During a mission to secure these cosmic relics, he fixates on UMA, an enigmatic entity tied to the Star Drops, deeming it indispensable to his ambitions. After clashing with space inspector Mary Ann and briefly facing capture, Burn stages a daring escape. He later brutally confronts Lala of the Pretty Cure team, overpowering her to seize UMA. This reckless act destabilizes UMA, triggering its monstrous expansion and plunging Earth into imminent peril. Burn’s unyielding greed escalates the crisis, compelling the Pretty Cure to intervene and avert planetary annihilation. Post-conflict, Burn is subdued and apprehended by Mary Ann alongside his fellow Alien Hunters. His narrative centers on unchecked avarice, driven solely by a covetous desire to hoard power, with no elaboration on origins or redemption in canonical sources.
