Gabara is the main antagonist of the 1969 kaiju film All Monsters Attack (aka Godzilla's Revenge), the tenth Godzilla film.
Gabara is a monster apparently created in a boy's mind, and he picks on Godzilla's son, Minya, whenever he gets the chance.
Gabara first appears wandering through the forest and is spotted by the boy Ichiro and Minilla. They hide and Gabara doesn't see them and leaves. Minilla admits to being afraid of Gabara, and Ichiro reveals he is bullied as well. Ichiro wakes up but falls alseep soon after. The first monster he encounters is Gabara. Ichiro runs but Gabara has seen him and follows him. But Ichiro is nimble and quick, and easily escapes. However, Gabara keeps on his trail and finds him and Minilla watching Godzilla fight Ebirah and Kumonga. Gabara challenges Minilla, who accepts because he doesn't want to look like a coward to his father Godzilla. Minilla is at a physical disadvantage, being smaller, and so tries to hit Gabara with atomic rays, but they are not strong enough because he is too young. Gabara mocks him, prompting Minilla to charge head-first at his enemy only to get beaten senseless. Clearly losing, Minilla retreats. Gabara gives a roar of victory and wanders away.
Gabara finds Minilla later on and fights him again. Gabara is clearly winning and pummels Minilla, and reveals he has the power of electrocution through physical contact and shocks Minilla into unconsciousness and punches him to the ground. Ichiro comes to the rescue and drops a boulder on Minilla's tail, causing him to fire an atomic beam right into Gabara's face. Enraged, Gabara charges at Minilla, who dodges his attacks. Godzilla arrives but wants Minilla to fight Gabara alone. After a brief battle Minilla and Ichiro form a plan. Gabara approaches Minilla and steps on a log, and Minilla jumps on the other end and sends Gabara flying. He crashes to the ground and whines about his defeat and is kicked by Godzilla. Gabara wasn't done yet and instead attacked Godzilla, who fought back. Godzilla was electrocuted but managed to gain the upper hand and flipped Gabara over his shoulder. Gabara retreats limping back into the forest and doesn't bother Minilla again.
