If you want to remove the Hero2 object from the new City world, you will need a reference to that world; and you will need a reference to the Hero2 object in that world:
?
1
2
3
City city = new City();
Greenfoot.setWorld(city);
city.removeObjects(city.getObjects(Hero2.class));
By the way, your 'getWorld' method call on line 6 still returns the world where the click occurred. The line is equivalent to:
?
1
this.getWorld().removeObject(< Hero2 object reference >);
where 'this' is the actor in the "then" active world that caused the act method to execute.

If you had the Hero2 object reference in an instance field and a method to return that Hero2 object in the City class:
?
1
2
3
4
5
6
private Hero2 hero2 = new Hero2();
 
public Hero2 getHero()
{
    return hero2;
}
then you could remove it specifically with:
?
1
2
3
City city = new City();
Greenfoot.setWorld(city);
city.removeObject(city.getHero());
