Background
On October 25th, 2020, Marisa posted the first drawings of Nico in response to an ask message on Tumblr. Nothing about how he was presented insinuated he was anything but an original character.
The same day, she posted a comic. This post gained a lot more attention, and despite, once again, nothing in the post indicating it was anything other than fan content, many many people assumed the catboy was canon to the show. He didn't even have a name yet.
After seeing the amount of people who thought Nico was a real character without even trying to fool anyone, Marisa wanted to see what she could do on purpose, so she made fake screenshots.
Over the following months, Nico became widely and well received across Tumblr. He received lots of fanart. Even still, Marisa continuously got messages from people that thought Nico was real. (This still happens to this day.)

Zine
By February 2021, Marisa had made enough comics and art of Nico to fill 50 pages of a zine. She sold over 200 copies of the physical zine, and even more of the digital zine, which is still available for purchase here.
Nico (full title: Nico the Catboy) is an original character created by Marisa BeBeau (known as by @sabertoothwalrus on Tumblr). He is a catboy and Finn's boyfriend.

Polls
In January 2023, Tumblr added polls. Users began creating brackets, mimicking Twitter's "Tumblr Sexyman Poll," including their own "Tumblr Sexyman Rematch."
On February 20th, a blog called @blorbopoll (run by @cherrystrawberrie) created a bracket for the "Most Iconic Tumblr Blorbo," featuring Nico the Catboy as one of 32 contestants. Despite no one regularly posting about Nico in over a year,
Nico managed to beat Taako (from the DnD podcast, The Adventure Zone) with 52.8% of the 35,035 total votes. In other words, at least 18,498 people voted for Nico. In the second round, Nico was paired against Marshall Lee, a canonically not-canon character from Adventure Time, and won with 67.8% of 12,567 total votes (8,520 votes going to Nico). Unfortunately, Nico lost the third round to Miette, a cat from a popular tweet.
