Master Kohga

Master Kohga is a boss in The Legend of Zelda: Breath of the Wild. He is first met as a character, Kohga, the leader of the Yiga Clan. During the fight in the Yiga Clan Hideout, he will switch between a variety of boulder based attacks. He can be defeated by using the Stasis Rune and Magnesis Rune to stun him with his own boulders. Once stunned, most conventional weapons deal damage, but ranged ones will definitely be helpful as he often moves rapidly around the boss area. Eventually, he will unleash a massive boulder (large enough to obscure his view of Link), claiming it to be the ultimate technique of the Yiga Clan. However, the boulder ends up rolling towards him and falls down with him down the pit, with him declaring that the Yiga Clan will avenge him. He also has a dumb belly, according to Link.
