"An Evil Ascends", known as "The Day the Devil was Born" in the Japanese version, is the one hundred and twenty sixth episode of the Yu-Gi-Oh! ARC-V anime. It aired in Japan on October 9, 2016 and in Canada on January 19, 2018. Nicktoons aired on July 14, 2018. It became available with official subtitles via Crunchyroll on November 22, 2017.
As Yuri attempts to turn Sora into a card, Yugo appears before him and challenges Yuri to a Duel. While a fierce battle between Yuri and Yugo unfolds, Yusho, as well as Declan and others, manage to reach Leo Akaba. Leo begins speaking about the Devil Duelist who leads the world to destruction as well as the four dragons. What is the reason that the world is divided into Four Dimensions?
During the flashback scene, there is a silhouette of a duelist coughing out blood after his monster was stabbed by Beast King Barbaros. In the English Dub, this scene was removed.
One of the poses made by the holographic woman with the car is cut from the dub.
All scenes of Z-ARC's attack on the Original Dimension are given a purple filter in the dub.
Leo's comments, one made when Z-ARC reveals that he will destroy the world just before summoning his Four Dragons and just before Z-ARC and the Four Dragons fuse together are cut from the dub.
Leo’s voiceover describing Supreme King Z-ARC’s power while Yuya is screaming in anger is left out in the dub.
Z-ARC’s desire for power is changed to a desire for a greater challenge in the dub.
Surprisingly, this episode's violent content was left largely unaltered in the dub, save for a couple of scenes. In the end of the dubbed version of the episode, Leo makes a direct reference to death (a extremely rare occurance in Yu-Gi-Oh! English Dubs), saying that he was willing to pay with his life to stop Z-ARC. Similar references are made in the dubbed version of the following episode.
The eye of "Odd-Eyes Dragon" is sometimes colored in yellow instead of green.
