Gigabari is a mini-boss appearing in A Link Between Worlds.
The strategy of defeating them is similar to a Bari, although the boss takes more damage before splitting. When Link strikes it with his Sword, he will fly backwards like a Hardhat Beetle. When defeating the Biris, its best to use a ranged weapon like the Bow, Hookshot, or the Great Spin.
In Lorule Castle, a purple variety exist which behave the same.
