The getFighterPoints function is created as a helper, to produce a list of the fighters points. The issue with it is that it allocates the resulting array with only 1 item. This makes it impossible to use for any practical purposes, because client code would be interested in more fighters than the first one.
Another concern with the function is that it could become impossible to use if enough fighters are created. A big enough array would DoS the function. Consider providing it with a range of indices.
In this way you would limit the return data.
