Alien Prisoner 303 (宇宙囚人303 - Uchū Shūjin 303) is the 7th Episode of Ultraseven.


Aboard Space Station V3, agent Mizuno receives multiple transmissions from an alien source, but has been unable to decipher them. Meanwhile, two hunters find a small, single passenger alien spacecraft in the woods and are attacked by the fish-eyed, gas drinking alien traveling inside. Upon transcribing the messages, it turns out the monster is a murderous fugitive escaped from an intergalactic prison known as Alien Quraso. The Ultra Guard members and local police seek him out before the beast can kill more people. After the monster kidnaps Anne and hijacks one of the ships that make up the Ultra Hawk 1, the chase is on.
