Film: Phantom from 10,000 Leagues (1955)
Height/Weight: That of a hefty human.
Summary: If your first few thoughts after becoming a radiation victim are along the lines of "kill me", then don't feel alone, because it sucks. In fact, it sucks for all life forms. Even if those life forms are flesh-eating marine reptiles.
History: People are disappearing and reappearing dead and burned, there is a radioactive rock at the bottom of the ocean floor, and Professor King has himself to blame. This marine biologist has been tampering with the local sea life and the atom for some time now, and one of his (in?)voluntary creations is on the loose. That creation in question is a mutant reptilian beast stuffed to the scales with radiation.
Notable Kills: See Powers/Abilities for info.
Final Fate: King ends up having to go down to dispose of that irksome radioactive rock attracting the beast, but it ends up catching up to him. And before you know it, the bomb King planted there goes off, killing mad scientist and monster alike.
Powers/Abilities: The reptoid is radioactive to the touch. Quite literally actually, as one touch can result in deathly radiation poisoning.
Weakness: Anything conventional.
Scariness Factor: 2-Yes, it can give you deadly radioactive burns, but how could anyone stay afraid of this thing? It's a guy in a very clunky suit paddling awkwardly. In a way, it's kind of cute.
Trivia: -Actual marine reptiles include turtles, snakes, and the Marine Iguana, the latter of which can only be found on the Galapagos islands.
-This was one of the first films of its time to prove that double billing was a very financially savvy move.
