Dr. Mel Practice is the science officer of space station R.U. Sirius. He is a typical mad scientist, often creating killer robots and ray-shooting machines. Although he lacks scruples and often creates seriously dangerous devices, most of time he is not really evil. His young assistant, Winky, is the eternal victim of his crazy experiments. Some of Dr. Mel's inventions include: the procrastination ray, which sends problematic objects to the future, so that the user can deal with them later; the giant sentient computer PAL 8000, which is similar to HAL 9000 from the book 2001: A Space Odyssey; 4-D glasses, which should not be used when watching a 3-D film, otherwise you will foresee the ending; a time machine; and much more.
