The Bit Sniper is a Pureblood Heartless found in Kingdom Hearts. It only appears during the final battle with Ansem and the World of Chaos at End of the World, which makes it one of the eight enemies that do not have an entry in Jiminy's Journal.
The Bit Sniper has a simple, but surprisingly frightening appearance. It has a large, black teardrop shaped body, black bat wings, which enable it to fly and crawl around, the classic Heartless jagged jawline, and bright yellow eyes; looking closely around the eyes, blue vein-like patterns also can be seen.
The Heartless's name is a reference to its relatively small size, low strength and its ability to fire its lasers from long distances. A "bit" can mean a small amount of something, and sniper rifles are accurate weapons that can hit targets from considerable distances.
The Bit Sniper is largely ignorable during the last fight with Ansem, but can be quickly defeated to provide HP Balls. Its lasers can stagger Sora, so he should fly in a serpentine pattern to dodge them, and avoid their lunging attacks.
