[Tazzilla88]

Enma If were only counting Animal/insect/natural summons No contest!

Edo madara if human summons

And Juubi (gedo mazou) if were talking overall summons.

Enma over Katsuyu? Katsuyu has the advantage of being able to tank attacks elemental and physical. She has healing abilities, can absorb people. Can spit acid, And can crush people.
