The Giant Demonic Beast (Japanese: 巨魔獣 Giant demon beast) is a monster class which debuted in Fire Emblem: Three Houses. They are humans that have been turned into gargantuan monsters by the power of a Crest Stone.

Though the Giant Demonic Beast lacks proper programmed stats, they are defined by having immense strength, high defense, and three gargantuan health bars, even when compared to other Demonic Beasts. When their health is low, they become even stronger thanks to their abilities, and their latent abilities increase their power and physical durability yet further. However, they retain most of the same weaknesses that other Demonic Beasts do, including low resistance, speed, and movement, and their large size hindering their mobility further.
