Fan Casting Super Swimming Skills in Sort by Tropes

In the real world, swimming is a skill that usually must be learned over a period of time—and that's just for swimming on the surface. Swimming underwater is another skill all on its own that must be learned, and even then, no human can stay under for more than a couple of minutes or so at the most without the aid of some special equipment, or some continuous training to boost lung capacity. In fiction, however, this appears not to be the case. Video games are the biggest offender here. Any character that doesn't have Super Drowning Skills has a completely natural ability to swim like a fish, even if they've lived out in someplace like a desert their entire life.
