Hercules is the older twin while Zoe is the younger twin and Hercules often calls his sister "Zozo" as a term of endearment.

When the other Louds go to Aunt Ruth's house and Zoe is about to go with them, Lily cries loudly which makes Zoe stay at the Loud House to babysit with Lincoln, Hercules, and Clyde.
