M-Class 002: Titanic
Danger level: High
Population: 1
Titanic resembles that of the actual Titanic, because it is. Our team was attempting to find an alternate reality where the Titanic didn't crash into the iceberg, and instead found this. From afar, it appears to be nothing more than a normal ship, but on closer inspection, it's revealed that it is not in fact a normal ship. Of course, you won't be getting a closer inspection before it eats you. If you're out at sea, and spot the Titanic, get out as fast as you can.
