Lord of Mountains

Lord of Mountains resembled a great tiger fitted with broad wings like an eagle's, and a living snake served as her tail.

Formed out of the resentment of animals chased from their homes by people, she was ruled by loathing and a thirst to avenge them against all of humankind. Anything manufactured or technological repelled her, and she recoiled in disgust on learning that Genos was a machine, spitting that he was a cursed man-made thing. Mercy was not in her nature; she flatly refused to spare the cyborg even as he pleaded.

Lord of Mountains begins by spreading terror through City Z, announcing her origin and her vow to punish humanity. Told that a hero has come, she wonders whether Genos would dare face her. After a flicker of fear, Genos draws her toward a warehouse where he hopes Fubuki will lend a hand, but Fubuki has already gone, leaving him to fight alone. Declaring the warehouse his grave, the monster opens with her Great Mountain Wail, which throws him off his feet, then follows with a Volcanic Shot that slams him into a wall. When Genos begs for mercy, she only grows more furious at the sight of his machinery, coiling around him and promising he will feel the rage of every creature humans cast out. He wrenches loose and escapes into the open.

Impressed that he broke away, she calls up a Weather Change, wrapping him in a whirlwind that hurls him skyward, pelting him with a hailstorm, and finishing with a bolt of lightning to the head. Certain of victory, she laughs, only to find Genos standing behind her, that final jolt having jarred his lost memories back into place. Her punch is caught with ease, and Genos lifts her off the ground, telling her he will take away her anger as thanks for restoring his mind before erasing her with an incineration cannon. While Genos was amnesiac she managed to crack part of his arm and shoulder with her strength, speed, and weather-bending attacks, yet the moment his memory returned she was left utterly powerless.
