I must admit to being wildly unconvinced by the virus page which starts off by talking about bacteria "and other microbes, such as viruses and fungi" living on a space station. As a later link says, scientists disagree about whether viruses are living or nonliving organisms, because they can't reproduce themselves. But hey.
I use Pokemon in teaching, sometimes. I explained the concept of earthing to one of my less-gifted students by reminding him that Electric attacks have no effect on Ground Pokemon - because they go to earth. He understands it, now.
