Greg Berlanti did hint on having Power Girl appear on The Flash. In DC continuity, Power Girl is an alternate Kara from another Earth. I have literally been waiting for that since World's Finest. They better introduce her soon, seriously.Though why on The Flash? I get that he's the primary multiverse traveller in the DC Universe, but it's Supergirl's doppleganger and she now has a way to travel to different earths. But then again,

Fun Fact: Not only is Power Girl an alternate earth doppleganger of Kara in DC continuity, she is the Earth Two​ doppleganger of Kara. So this would support her appearing on the Flash, since the alternate Earth Team Flash interacts with the most frequently is Earth Two.

Either way makes total sense and is cool to me anyways. But think about it! Earth Two is already introduced in the Arrowverse, Supergirl is already introduced in the Arrowverse, Power Girl MUST exist on Earth Two by default, and I have a gut feeling that they won't make us wait that long for her introduction.. Heck, she's probably a famous superhero there and Harry and Jesse Quick even know who she is, and probably knows her personally.

Between you and me, I personally think they're holding off Power Girl because they don't think Melissa has the bust to pull of PG's infamous boob window.
