Pyro's YouTube channel was started July 27, 2013. Originally chiefly MLG montage parodies (which he claims to be embarrassed about) were uploaded to the channel. On October 30, 2016, a video was released on Pyrocynical's channel titled "IT'S JUST A PRANK BRO," a commentary-styled video which was a noticable deviation from the montage parody content. From then on, only one other montage parody video was released on Pyro's channel titled "SHREK HAS SWAG 2." Though the title was as so, the video was a commentary video, and though technically the video was SHREK HAS SWAG 2, the actual montage parody was not the bulk of the video and the actual montage parody was short compared to his actual montage parodies. Pyro's content as of 2017 is a mix of trending topics, gaming videos, and commentary.
Pyro's emblematic trait is his deep British-accented voice, some say he sounds as if he were "40 years old". Pyro's commentary videos mostly have gameplay of first person shooters in the background, notably a Steam game on "Counter Strike: Global Offensive" and "Overwatch". An early exception of this is when his fans convinced him to put "Connect 4" gameplay in the background. Later videos display gameplay of "Garfield Kart" (advertised in the descriptions as "clinical depression"). Pyro claims he has compiled over 12 hours worth of Garfield Kart footage and 100 hours of total gameplay.
As seen in a number of his videos, Pyrocynical's name is Niall. Evidence can be seen with various tweets, an image from his desktop showing his CV in a word document, and during a Drama Alert appearance where Leafy refers to him as "Niall".
Pictures of his face have been leaked from his private Facebook page by the host of DramaAlert, Keemstar, to Twitter. Although, Keemstar has claimed that he has never leaked information from Pyrocynical's private Facebook page and the picture that he has tweeted has already been leaked on Twitter and Google Images.
However, Pyro uploaded to his public twitter a video of him brushing his teeth, which has since been deleted.
On October 12, 2016, Pyrocynical unexpectedly uploaded a video of his face reveal, titled who i'm voting for president (face reveal) Mocking the Casey Neistat controversy about the 2016 presidential election. He has included a face-cam in many videos since the reveal.
He has made a lot of collaboration and gameplay with another Youtuber such as NFKRZ (who made his old intro animation) and Bamanboi. He can also be seen with Youtubers such as Jameskii, Squizxy, and Dolan Dark.
Pyro made several positive effects on other Youtubers such as LtCorbis where he promotes her channel.
Pyro is frequently criticized for being a LeafyIsHere clone due to great similarity of their content, and Pyro responded by self deprecating himself by making more resemblance to leafy by using click-bait and like-scamming. Despite all of the drama, Pyro and Leafy remained friends and appeared on Drama Alert with a playground insult match.
However, a video later made by HeyWatchYourMouth, a friend of Pyrocynical's, later claimed that Leafy secretly hates Pyrocynical and believes he ripped off his style, though this is currently unconfirmed and both Pyro or Leafy have yet to respond to this.
Just like others, Pyro has a negative view on Drama Alert, but still participated in the series.
