CW’s ‘Supergirl’ to end after upcoming season 6

CW's popular series 'Supergirl' to officially end after season 6.

According to reports by Variety, CW and producers Warner Bros. Television have jointly made the decision to make the upcoming sixth season of "Supergirl" as its last.

Writers are geared up to develop storylines for the final 20 episodes of the final series. Production of the series will begin later this month. The network is aiming to premiere the sixth and final season sometime in 2021.

The most recent season continued to star Melissa Benoist as the titular heroine, who also happens to be Superman's cousin. She addressed the show's end via social media.

"To say it has been an honor portraying this iconic character would be a massive understatement. Seeing the incredible impact the show has had on young girls around the world has always left me humbled and speechless. She's had that impact on me, too. She's taught me strength I didn't know I had, to find hope in the darkest of places, and that we are stronger when we're united. What she stands for pushes all of us to be better. She has changed my life for the better, and I'm forever grateful," Benoist wrote on Instagram.

"I'm so excited that we get to plan our conclusion to this amazing journey, and I cannot wait for you to see what we have in store. I promise we're going to make it one helluva final season."

News of the cancellation of the series comes almost exactly four months after the season 5 finale. 'Supergirl' debuted on CBS Oct. 2015, before moving to CW from season 2 onward.
