POWER COUPLE

When the two leads are equally strong and witty. It makes great interactions between them and a great plot. 

They might : 

1 - Complete each other. Like in "Black Panther": T'Challa & Nakia. (As a king T'chall could have summoned Nakia but he respected her ideals and dreams and created a foundation for her to run, in order to keep her in his life meanwhile she is free to follow her call to help those in need).

2 - Go against each other. Like in "Mr and Mrs smith". (Mr and Mrs Smith are in antagonistic roles Unknowingly or Knowingly).

3 - Help one another. Like in "The Double": Duke Su and Xue Fang Fei (Although being equally strong, one of the leads surrenders to the other, in order to help him like XFF willingly became Duke Su's pawn).
