Cynthia VS Diantha

[Captain Cadaver]

Both of these female champions have some comparable strengths and weaknesses. Cynthia is often praised for her diverse and powerful team, but Diantha has a few Pokemon higher levelled than Cynthia's best in her chateau rematch (not counting B2/W2's challenge mode). Because of Cynthia's many appearances, she'll be using a team best suited for her opponent, but there will be two moveset scenarios based on what Mega she uses.

I have no idea who Diantha is, but why is there such a large discrepancy in the levels of pokemon on her team?

 

[Captain Cadaver]

She's the Kalos Champion from X/Y. The reason for the difference in her team's levels is due to her only using 4 of them in her later Battle Chateau rematches (the 4 that are Level 80), whereas her team and levels don't change in Pokemon League rematches for some dumb reason.
