1. What are the main differences between a Motherbox and a Fatherbox, is it just an aesthetic difference since they have Mobius tech/operating system or is there something only or the other can do that the other cannot?
2. Out of universe why wasn't Spectre and the Golden Age Hawkman part of the Justice Society of America on Earth 16? Not asking if they exist on Earth 16 only what made you decide not to use them as members of the JSA in this iteration?
3. On Earth 16 what does the Courage of Achilles and Stamina of Atlas do for the Marvels? Sometimes one provides invulnerability over the other and vice versa, so what are the main powers that they provide?
