When shooting lightning, it tends to be treated as a sort of beam you can aim and shoot anywhere. This doesn't make a whole lot of sense — lightning is a really big static charge, like you get all the time when you're wearing sweaters. Static electricity will leap from something with high potential to something with low potential; the only way to aim it should be to modify the potential of both yourself and the target, in which case, it would be impossible to dodge. All this is always ignored. Sometimes their power is called "thunder," which is a cool-sounding misnomer.
