Super Hero Powers covers a wide range of fantastic abilities, every single one of which the author has imagined having at some point.
Defining super hero powers is tricky. We can all agree that flying (sans plane, copter or jetpack) is definitely a superhuman ability, even if the individual in question uses farts for propulsion. One defining characteristic of a super power is that it is integral to the person's body. For example, having bionic limbs that give you superhuman strength would count as a super power. Having a gun that allows you to kill at range doesn't count. However, having a gun welded on to your arm would count as a super power, unless you had to use your other hand to pull the trigger, in which case it merely counts as stupid.
