There have been many rumors about who runs the channel, which now primarily posts Fortnite Battle Royale content, linking some of the most high profile streamers and YouTube stars to the project.
As an April Fools' joke, H2O Delirious decided to post a video that - at first glance - might have seemed like a face reveal video. However, that wasn't entirely the case.
The video, posted on April 1, showed a series of people revealing that they were the real H2O Delirious with selfie cameras - one of which was popular Pokemon Go YouTuber Ali-A.
While many of the posts were short and sweet, a longer clip was presented at the very end featuring Ninja, leaving some fans wondering if it was him all along.
"I know that there's a lot of speculation going on and I just want to set the record straight," Ninja said during his April 1 stream. "I am H2O Delirious. I have been a YouTuber for a long time and I started out with Call of Duty and doing a lot of simpler games, so I just felt it was time for you guys to know."
The clip has been saved and shared on several media platforms since, including Twitch, Twitter, YouTube, and was even retweeted by Ninja himself.
Many of his fans will notice that there's a voice changer at work in the clip, though, and that this 'revelation' is more than certainly a joke.
YouTuber Ali-A, who recently eclipsed over 10 million subscribers on the platform, also created a mock reveal for H2O Delirious. "Hello! This is my face," he said during the video. "H2O Delirious! Yep, that's right. H2O Delirious."
Ali-A has since responded to the clip on Twitter, too, adding that he thinks it "came out so well."
Hahaha that came out so well! xD 👌🏻— Ali-A (@OMGitsAliA) April 2, 2019
For those that are not aware of who H2O Delirious is, well, the real answer is that nobody really knows. However, the channel has over 11 million YouTube subscribers and 4.3 million Twitter followers at the time of writing.
Whether or not the true identity behind the project will ever be revealed is unknown, but it's not either of Ali-A or Ninja. That's for sure.
