Edit
An alien creature from the Macross 7 science fiction series from the 90s.
Glavil (グラビル Gurabiru) is a giant, muscular Protodeviln monster with tentacles on its back and is usually perched on all fours like an animal. He represents pure, untamed fury, crushing everything in his path, and generating enormous energy fields which rip apart all around him.
Glavil can also fire intense energy beams that surpass by far the Macross Cannon in power. His face can also redirect laser fire. He increases in size when he absorbs spiritia, which he can drain from lower life forms such as humans and Zentradi and even cause massive dehydration, but the energy of Anima Spiritia causes him to shrink, and after several encounters he flees instinctively from it.
Lacking any discernible intelligence of his own, he is frequently given instructions by Gavil, the other half of an even more powerful being.
