But in 4b they were all playing for the same team as partners. Rumple, Maleficent, Cruella, Ursula, Isaac, Zelena... See this: http://tvtropes.org/pmwiki/pmwiki.php/Main/BigBadDuumvirate It also says this: From what I understand, the villains need to be on the same level and relevant to the plot. That's why Cruella and Ursula are not mentioned because they were always one level under Mr. Gold and honestly, Ursula was barely a villain, let alone a character, so I really don't think she qualify as a "Big Bad". Zelena wasn't relevant to the plot, that's why she's not the Big Bad of 4B.
 * Season 4: Mr. Gold and Maleficent initially, and it remains so for most of the arc until the 3rd-to-last episode when she leaves his side after Cruella 's death. After this, it becomes a new Big Bad Duumvirate with Gold and Isaac. We also have Zelena as well, who is in league with Gold but doesn't end up doing much for the overall plot.
