"Right now my priority is preserving everything he's built and I don't have any plans beyond that. His channel was one of his greatest accomplishments, and while we all need our time to mourn him, I know he wouldn't want it to end like this," she wrote.

Hassan Khadair, the Comicstorian fan-turned-pop culture host for the channel, paid tribute on Instagram, adding that "the other greatest joy was having Ben Potter, the guy who I loved watching so much, become my mentor and one of my best friends."

"Benny was over a decade into a successful YouTube career and frankly he was just getting started! We had so much wonderful stuff planned and I hope to be able to carry on his legacy and honor him in whatever way I can for the rest of my life. Love you forever Ben," Khadair wrote.

Khadair said Potter "had the most powerful, booming voice and simultaneously one of the most loving, warm, inviting presences."
