Film: The Atomic Submarine (1959)
Height/Weight: As big as a small house.
Summary: When danger arises, the Atomic Age finally decides to stop screwing up! Enter the Tigershark, the largest atomic submarine! It's no Nautilus, but when it comes to evil aliens seeking to subjugate the world, it gets the job done.
History: This alien cyclops has been to and studied hundreds to planets with one goal in mind: find one ripe for conquering. And not only that, but use the natural life to construct his race's machines. Yes, everything they make can be considered techno-organic. For instance, the saucer he was in was very much alive as he was. It took forever, but eventually, he settled for Earth, and made his home base the watery underbelly of the North Pole. But when his ship's presence started causing problems for passing ships, the Tigershark submarine was called into action.
Notable Kills: He uses the ship to melt two guys with radiation and crush another with a large automatic door. It's a rather brutal security system.
Final Fate: After getting shot in the eye with a flare gun, the alien blindly rushes out of the waters of the North Pole to return to his planet...only for the saucer to get obliterated by a missile from the Tigershark.
Powers/Abilities: Aside from telepathy, the alien's living saucer comes with a special radioactive anti-intruder system. It melts people's skin off.
Weakness: Anything conventional, though the saucer requires heavy artillery.
Scariness Factor: 3-The UFO may be a credible threat, but as for the alien that boards it, he's a bit on the helpless side. Seemingly immobile and unable to fight, this guy's huge eye is...well, an eyesore distracting from his rather octopus-like body.
Trivia: -The cyclops was voiced by John Kenneth Hilliard, who's credited for his developments in theatre sound design.
-This was the last film to feature actors Victor Varconi and Jack Mulhall.
