The Captain Marvel Family vs. the Thor Family

No prep. Characters are at normal levels.

Marvel Family:

Captain Marvel
Lady Marvel
Captain Marvel Jr.

Thor Family:

Thor
Beta Ray Bill
Thunderstrike

lady marvel? capatain marvel junior?

They possess one-third of the Shazam power. CM gets two-thirds. Lady Marvel and Cap Junior share a third.

You should add Black Adam in the Marvel family. Would tip the scales.

Thor family wins.

Black Adam? Sure. Why not? Replace Lady Marvel then.
