Digigex90 joined in the fandom around mid-2012, when he saw the episode "Hearth's Warming Eve", although he knew of MLP:FIM for a brief time when he saw Jitterydragon's YTP videos. He started as a fan fiction writer when he saw a forum post of Rainbow Dash vs Rodan. He was also inspired from a few other fanfic writers: JusSonic first, Bigdream64 second, then Courageous-of-Light last, over a span of one year or two. It wasn't until somewhere around 2016 to 2017 when he decided to be an artist and a YouTuber.
He started drawing around 2012-2013 and wasn't very good, but over time, he has improved a bit. He still has stuff to learn before being an expert of drawing stuff.
During his time with YouTube, he used to do YouTube Poop vids of Gumball after being inspired from Jitterydragon, but he stopped doing it after he realized he really sucked at doing them. Because of that, for a while he did Let's Plays and MUGEN videos. In 2014, he moved channels to Digigex90 due to unknown reasons. In 2015, he tried to do a review of the season 5 premiere and the third episode, but stopped doing it after a while due to laziness and work with high school. But in 2016, he announced that he would return to do reviews again along with announcing other things, like his retrospective series.
As of 2018, he currently does reviews of video games, TV shows, and movies. He also does retrospectives of franchises that he grew up with as a kid and a teenager.He occasionally does speedpaints and Bakugan brawl videos. He later started the Yugioh: Duels of the Cyber realm series after being inspired from Yugibrony.
Sometimes he'll try other things for experimentation whenever he gets inspired from someone. He's still doing art of MLP, and occasionally other franchises on Deviantart.
As of January 2019, Digigex hasn't done another fanfic, and it's unknown if he will ever get back into Fanfiction writing.
