Supergirl vs Reign

So, I've been thinking about Supergirl's first 2 seasons.

Don't get me wrong. I loved them. But something has been lacking. A REAL threat to Supergirl.

I'd love a really big fight between Supergirl and Reign. This series has sorely lacked REAL physical threats against Supergirl, and that's exactly the type of possibility Reign could present.

Season one just didn't have the right fight choreographers or budget, due to CBS and filming in LA. That's why half our fights were heat vision based. Season two had marked improvements in production quality and fight choreography. But all the "big threats" went down too easy. The cage fight in S2e4, "Survivors", could have been good, but it was barely a fight at all. There was real peril with Parasite, and how he drained both Supergirl and J'onn, but again, not really a fight. Just a quick draining scene. And in both of those episodes, when Kara has her second encounters with the villains, she beats them instantly...it just doesn't emphasize that they were ever a real threat to the Girl of Steel.

The fights with Henshaw in "The Darkest Places" and Superman in the S2 finale came close. The latter far more than the former.

I'm looking for a threat that's equivalent to how Merlin/Arrow's or Ra's/Arrow's first encounter, or the first fight between Flash/Reverse Flash, or Flash/Zoom.

In all of those examples, the hero was defeated. Overwhelmingly. But this set the tone for the rest of the season. It established just how dangerous their villains were, and how far the heroes had come when they defeated them in their season finales.

The best example, to me, is Flash/Zoom's first encounter. It was brutal. I'll admit it. But as savage as Barry's defeat was, it really showed, for the rest of the season, how Zoom was basically the "boogeyman". Barry really hesitated to get back in the saddle, so to speak, and it was a season long struggle of figuring out the best way to handle the threat.

Of course, in the end, we want our heroine to win. But those wins, in my opinion, just aren't as awesome as those of her male counterparts, until the villains are shown to be just as threatening to her as Merlin or Ra's was to Oliver, and Zoom or Reverse Flash was to Barry.

There is also the issue of Kara's enemies, who are supposedly super powered, constantly running away when Alex or the DEO show up with standard issue firearms that shouldn't be able to harm them. It really downplays how much of a threat they should really be, or why they needed Kara in the first place.

I'd like to hear your thoughts. Would you like to see a scenario where Supergirl is defeated, at first, emphasizing Reign's threat, only for our Girl of Steel to win a rematch in the season finale?
