10 Comics Too Big To Fail (That Did Anyway)
10. The Unbelievable Gwenpool
The Unbelievable Gwenpool first appeared on a variant cover of Deadpool's Secret Secret Wars, and despite not appearing anywhere in the comic, the character was a huge hit among fans. It wasn't long before she showed up again in a holiday special one-shot as a secondary character to Howard the Duck.
From there, she got her own series, The Unbelievable Gwenpool debuted in June 2016, and the fans loved her. The storylines were original, the character was funny, and the fourth-wall breaks were perfectly written. Sadly, they also foresaw the series' cancellation, as it only ran for a total of 26 issues, ending in April 2018.
The series had a dedicated fan base, so it was a surprising cancellation. While it may have been something the readers weren't expecting, Marvel didn't hesitate to order the series conclusion after less than two years of publication, and the reason is actually pretty simple.
The books may have had a lot of fans, but not enough to justify the expense of publishing the comics. Sales numbers were low, and Marvel axed the book alongside a bunch of others in early 2018. Seeing as the character remains popular among fans, it's likely she will reappear one day, but there's no telling when she'll land a series of her own again.
