1 - Regina, obviously. She was the one who cast the curse, and was the biggest threat to Emma trying to break the curse.

2A - Cora. Hook could be considered kind of a secondary villian too.

2B - Greg and Tamara, although they are just puppets for Pan.

3A - Pan.

3B - Zelena.

4A - Most likely Ingrid. Even though all she wanted was a family, she still counted as the big bad. Gold was a secondary villain too.

4B - Gold and Maleficent probably posed the most threat. Cruella could be included too. I guess you could add Isaac too.

5A - Nimue and the darkness. Emma and Hook were like puppets. Arthur was a wannabe.

5B - Hades is the big bad. Cruella, Pan, James, Gaston etc. were just puppets for Hades and only really posed a threat in a few episodes.

6A - Probably the Evil Queen. Jekyll and Hyde for the first few episodes. Gold and Jafar were minor villains.

6B - Black Fairy/Fiona. Gideon was being controlled by her so he doesn't really count.
