On November 15, 2019, Fischbach created a new channel with YouTuber Ethan Nestor (known online as CrankGameplays) called Unus Annus, a channel which planned to upload a video every day for one year, after which the channel would be deleted along with its videos. The channel had 1 million subscribers in its first 5 days and 4.56 million in its last few minutes. The channel was deleted on November 14, 2020. The channel was meant to remind viewers about life and death and how quickly both can come and go.
