Film: The Giant Behemoth (1959)

Alias: Behemoth, the Sea Monster

Type: Ancient/Mutant

Location: Ocean/Civilized area

Height/Weight: Twice as big as the London Tower.

Affiliation: Neutral

Summary: If there's anything Godzilla proved earlier, it's that radiation can hurt monsters as well as empower them. The Paleosaurus is a rather extreme example, as she became an instant threat to everything around her upon awakening, including herself.

History: In the Bible, it was predicted that the massive monster known as the Behemoth would herald the end times upon awakening. This eerie prophecy would eventually come true...sort of. Indeed, a giant monster rose from the depths upon getting hit by an atom bomb, and to make matters worse, the beast was emitting radiation constantly, slowly destroying herself as well as all around her.

Notable Kills: The people of the 50s had no idea that radiation poisoning could be so horrible to look at, especially when it's being concentrated directly at victims, turning them into irradiated mummies.

Final Fate: While in the River Thames, the beast gets a radium-infused torpedo to the face, sending her radiation levels into overdrive and killing her instantly. However, news soon begins to spread about scores of irradiated fish washing up across the eastern U.S. shores...

Powers/Abilities: Aside from sheer size, the Paleosaurus can focus her radiation into an electric pulse that can render anyone and anything an irradiated husk.

Weakness: The radiation that makes the beast so powerful is slowly killing her.

Scariness Factor: 4.5-Despite being portrayed by a cheap-looking hand puppet for a while, when the beast shows up in all her stop-motion glory, no one is safe. She's no Godzilla, but getting hit square in the face with an irradiated pulse is a horrible way to go. Then again, one must pity her situation, as she is constantly in pain.

Trivia: -The film was originally supposed to be about a giant irradiated blob, but that was changed to ape "The Beast from 20,000 Fathoms".

-This was the first giant monster film to be made in the United Kingdom.
