[10] In late 2015, Higgins was announced as the writer of Mighty Morphin' Power Rangers, an ongoing comic based on the show of the same name for Boom!
[13] The character's popularity soon led to inclusion in mobile fighting game Power Rangers: Legacy Wars, an exclusive action figure,[14] and other merchandise.
Beginning in March 2018, Higgins wrote the first Power Rangers comic book event in "Shattered Grid", incorporating a range of characters from across the show's history, to celebrate the franchise's 25th anniversary.
Starring Tom Riley and Britt Lower, the award-winning neo-noir follows twin private investigators born with a mysterious medical condition where only one of them can be awake at a time.
[15] In March 2017, Dynamite Entertainment announced a reboot of the Magnus, Robot Fighter franchise, written by Higgins with art by Jorge Fornés.
Higgins also reunited with his Gates of Gotham collaborator Trevor McCarthy for Nightwing: The New Order, an Elseworlds-style miniseries set in an alternate universe in which superpowers have been eliminated and outlawed.
Despite initial fan criticism of the premise,[18] the series was ultimately well-received, with many reviewers comparing the book positively to Marvel's concurrent Secret Empire event.
[24] A third series, The Mystery of Ultraseven, was announced to begin publication in August 2022, with Higgins and Groom returning as writers and Davide Tinto serving as the artist.
[25] In November 2020, it was announced that Higgins was writing another creator-owned book for Image Comics entitled Radiant Black, with art by Marcelo Costa.
It all started with a one-shot crossover entitled Supermassive, written by Higgins, Ryan Parrott, and Mat Groom with art by Francesco Manna and Simone Ragazzoni.
[29] In August 2021, it was announced that Joe Clark, music composer and long time friend of Higgins, would be joining as a permanent co-writer starting with issue 4.
