Contrary to the multi-defined view held by sites like VS Battles Wiki, here the ability of healing is the ability to heal yourself. This can range from healing wounds by your own willpower to returning to peak potential. It is not quite the same as regeneration, however. It does not necessarily be by your own abilities, either, as the possession of items that can aid you in this regard is enough to count towards it (so long as it is made clear the ability is via said item(s)). Mainly found in JRPGs in order to regain lost "HP".
