2014–2020
Kelly and Lanzing met and became friends when they both went to USC,[4] bonding over comics.[5] Per Kelly: "Comics let us write stories — stories weirder and more wonderful than Hollywood would ever dream of green-lighting — and then within six months, they can be on the shelves. In comics, you can actually tell stories that people can READ; for a writer, that's the first step towards happiness." Their first script together was "a Samurai vs. Feral Monster movie called Sundown."[5] Their first major comic writing credit was a 2014 four-issue mini-series with Boom! Studios called Hacktivist, where they collaborated with Alyssa Milano and artist Marcus To.[6] They followed that up with a six-issue sequel.
In 2016, they got their first writing job for DC Comics, where they wrote issues of Batman and Robin Eternal,[7] and then took over writing Grayson from Tom King and Tim Seeley.[8] Their first creator-owned series, published in 2016 through Boom! Studios, was Joyride, where they teamed up again with artist Marcus To to tell the story of some disaffected teenagers who steal a spaceship, which AiPT called a "space epic with a punk-rock attitude."[9] The book lasted twelve issues and they followed it up with Zojaquan, published in 2017 through Vault Comics, a fantasy comic about a woman who wakes up on a primordial world.[10]
In 2016, Lanzing became the gamemaster for the actual play series VAST which premiered on the Alpha streaming service by Legendary Digital Networks[11] and Kelly appeared as a player in the series.[12][13] In 2017, the second season streamed on Geek & Sundry's Twitch channel.[14][15] They were the lead writers and executive producers for Kings of Atlantis (2017), the "first-ever animated kids series from YouTube Originals."[1]
In 2017, they wrote Gotham City Garage, a mini-series set in a dystopian Elseworld inspired by DC Collectibles' Gotham City Garage statues.[16] Per Kelly: "Gotham City Garage is an anti-fascist anthem for the open road, starring reimagined takes on DC's great female characters through an outlaw lens. We're bringing Big Barda, Steel, Catwoman, Harley Quinn, Silver Banshee, Hawkgirl and the first Kryptonian this world has ever seen--the mysterious girl named Kara Gordon--into a world of bikes, outlaws and elaborate tattoos." The series lasted twelve issues.
In 2018, they took over writing the book Green Arrow starting with issue #48 and wrote it until issue #50, when it was cancelled.[17] In 2019, they became the writers for DC's six-issue gen:LOCK mini-series.[18] Also in 2019, they were announced as the showrunners of Star Trek: Year Five for IDW, which told the "final year of the Enterprise's original five-year mission."[19] Lanzing spoke at WonderCon 2019 about it: "To me it is one of the greatest unanswered questions of Star Trek canon: how did the five-year mission end? How did we end up where we begin in Star Trek: The Motion Picture? How do these characters – the last time we saw them in season three – function so strongly as a family and so strongly as a crew. How do we then find them splintered – particularly with Spock – at the beginning of The Motion Picture?[20]"
2020–present
The Star Trek series ran for twenty-five issues and ended in 2021.[21] In 2022, IDW announced that Kelly and Lanzing were the writers of their new Star Trek comic which would include bring together "characters from across the galaxy--and all eras and variations of the beloved franchise--who must band together to prevent the mysterious murder of the gods."[22] As of 2024, it is still ongoing and has spun off several other comics, such as Star Trek: Defiant.
In 2021, they wrote their first work for Marvel Comics, a five-issue mini-series for Kang the Conqueror.[23] Per Kelly: "We are hoping to, by the end of issue five, take you through the entirety of King's [sic] life. So that any Kang story that you have read over the course of the last several decades, you can look at it and see where it fits inside the secret history of Kang the Conqueror, and the personal story he's been through."[24]
