Supergirl vs. Power Girl

Supergirl and Power Girl have a strange relationship. Technically, they are the same person- but Power Girl is slightly older version of Power Girl from a parallel earth. This makes their interactions strange. Despite both being heroes, odd tensions exist between them.

Supergirl is furiously jealous of Power Girl. Her older doppelganger is more mature and respected. But, it's not just that: Power Girl is physically more mature as well. Supergirl is still thinner and shorter, with meager B cup breasts and a lean body. Power Girl is taller, more muscular and curvier. Power Girl is rather infamous for her DD cup breasts, which she shows off with a cleavage hole cut in her costume. At 19, Supergirl worries she'll never develop to match her doppelganger.
