As an example, there are a bunch of fighters, they have a to-many relation called "Enemies,"
so when say Nightman adds Batman as one of his enemies, Batman also adds Nightman as one
of his enemies, and when either Batman or Nightman takes the other off the list, then the other also reciprocates. Is this possible to set in the modeler, or would I need to just add some custom code in my Managed object?

Core Data does this automatically.
