The Fly Man is a rare enemy brought by the Time Traveller into the submarine.
The Fly Man is a scientist that has been fused with a fly, resulting in him having a fly head instead of a human head. Due to his unfortunate condition, the poor soul has descended into insanity and will mindlessly attack anyone nearby with his Chemistry Kit.
The Fly Man will attack anyone that approaches him with his Chemistry Kit. Although it is not particularly dangerous, it can cause a lenghty distraction, and greatly damage crewmembers if not dealt with properly.
- The Fly Man is a reference to the book The Fly. Its appearance is based on the movie of the same name. Notably, however, the Fly Man lacks a fly arm in the place of an arm.
