Dynamic Duo Damsels: Mighty Maidens and Leaping Ladies

The predominant female doppelgängers to their World's Finest Teams of the Supermen and Batmen of Earths One and Two were Supergirl/Batgirl and Power Girl/Huntress. Each had relationships as essential with one another as had their male mentors. Likewise, the gals' friendship was as strong as the guys whom they modeled their costumed careers after. And during the Crisis On Infinite Earths... these bonds depended. How so?

Their dynamic was such that there was a dominant and passive member to each Dynamic Damsel Duo, only reversed in each universe. On Earth-One, it was a Supergirl who provided the inspiration for a dejected Batgirl, feeling vulnerable perhaps for the first time in her caped crusading career. On Earth-Two, it was her cosmic twin the Huntress who needed to inspire Power Girl, despite the death of the Maid of Might's Kryptonian counterpart.

By the end of the Crisis, it was the weaker pair... Batgirl and Power Girl... who were left behind as their courageous best friends Supergirl and Huntress perished, attempting to protect their worlds from the mad schemes of the Anti-Monitor. Both of these women were erased in the composite Earth that was created in the wake of the Crisis.

However, on the Earth-Two that remained after the Crisis (in an alternate timeline indicated by past stories), Huntress continued to inspire her pal PG throughout the years to come. Meanwhile, Batgirl was left to reflect on her fallen friend who died so that the Multiverse could remain in one form or another.
