The Nightwing AI trend is the October 2026 TikTok trend built on Beth Cast's Nightwing costume post, where people use AI to remake her moves with themselves, streamers or characters. You lift the blue mask in your own clothes, flip it away and land in the suit, or a new costume, on the cut. People also call it the Beth Cast Nightwing AI trend and the Nightwing transformation trend. It is a different trend from the March 2026 Nightwing dance trend, known as the trend do Asa Noturna in Brazil.
Against a lavender wall, in everyday clothes, you lift the blue mask to your eyes, pull it off and flip it out to the side, and the camera whips after it. On the cut at about 3.7 seconds, you appear in the purple-lit living room in the black suit with the blue V across the shoulders and chest, mask on, dancing with two glowing batons in front of the white sofa and the starburst chandelier. Next comes a close-up of you in profile in the dark, a spin with one baton raised, and the closing pose with both batons crossed behind your head.
Beth Cast, a Mexican creator with 4.16 million YouTube subscribers, posted her Halloween Nightwing costume video on TikTok on October 6, 2026, captioned "Buenas noches". By October 24, 2026, it reached 14.5 million views and 2.7 million likes. On October 13, 2026, she posted it as a YouTube Short, where it passed 4.9 million views. The sound playing with the moves is "STEREO LOVE FUNK" by Cotneus, PVNZER and Kngmn, also called the "Stereo Love Funk" sound.
On October 18, 2026, @seihanstreams posted the first AI version on TikTok, where a Spanish-speaking streamer changes into a fairy-princess dress on the cut, passing 2.2 million views. More streamer versions followed in the suit and in a maid outfit. On October 21, 2026, a CapCut template went up and passed 13,000 uses by October 24. Today, people make their own with one photo, dancing in the suit or in a costume of their own as a Halloween costume try-on.
