The Nightwing AI trend is the October 2026 TikTok trend built on Beth Cast's Nightwing costume video, where people use AI to redo her moves with themselves, streamers or characters, landing in the suit or a new costume on the cut. On TikTok it also goes by the Beth Cast Nightwing AI trend or the Nightwing transformation trend. It is separate from the March 2026 Nightwing dance trend, which viewers in Brazil call the trend do Asa Noturna.
Each video runs 15 seconds. You start at the lavender wall in your everyday clothes, raise the blue mask to your eyes, and flip it away as the camera whips to the side. The cut hits at about 3.7 seconds, and you land in the purple-lit living room in the black suit with the blue V, the mask on and two glowing batons in hand. You dance by the white sofa and the starburst chandelier, cross the batons overhead, turn, spin, and hit a profile shot in the dark before your final pose facing the camera.
The trend started with Beth Cast, a Mexican creator with 4.16 million YouTube subscribers. On October 6, 2026, she posted her Halloween Nightwing costume video on TikTok with the caption "Buenas noches", earning 14.5 million views and 2.7 million likes by October 24. She posted it as a YouTube Short on October 13, where it passed 4.9 million views. The track plays "STEREO LOVE FUNK" by Cotneus, PVNZER and Kngmn.
Creators quickly started making their own versions. On October 18, 2026, @seihanstreams posted the first AI version on TikTok, showing a streamer who lands in a fairy-princess dress on the cut, passing 2.2 million views. Other streamers posted their own takes, some in the suit and one in a maid outfit. A CapCut template went live on October 21 and passed 13,000 uses by October 24 as people used the look as a Halloween costume try-on.
