From Kingdom Hearts Wiki: A world of information not accessible by Gummiship
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 if the player wants to restore their health, or if the lasers of the Heartless are causing damage, they can be defeated with a few quick strikes of the Keyblade. Its lasers can stagger Sora, so if the player is close to death, they should try to fly somewhat erratically to avoid them.
