If in subclass, I don't have an initializer method, does it affect anything at all??

In this video, SuperEnemy is subclass of Enemy. So before he creates an initializer, when he write the instance for SuperEnemy, it still works fine

This is what is called inheritance. When you call a sub-class, it can still inherit the super-class values and initializers.
