Before Critical Role began, Liam and his close friend Sam created a podcast called allworknoplay, with the intention to get more fun into their busy schedules. For Liam's birthday they planned to play Dungeons & Dragons with some friends and shared their experience on the podcast. Towards the end of All Work No Play's second episode, the two of them talked about getting ready for the upcoming "one-time" D&D game. Liam asked Matthew Mercer to run the game, because Matthew kept telling him about the D&D game he was running and often invited Liam to join. Liam enjoyed the game so much that he messaged the other players shortly after, asking if they would like to start a continuing game. They have been playing ever since.

Liam and Laura Bailey decided to play twins in Campaign One because they share their birthday, May 28th.[2] Before the game, the two of them spent about two hours at a diner creating their character backgrounds.[3]

Before they started streaming, Liam recorded snippets of their gameplay. One can be heard in the second episode of All Work No Play and another one is available on his yotube channel.

Main campaigns[]

While playing as Vax'ildan in Campaign One, Liam came up with a backup character, a "halfling druid/monk from the Air Ashari, sent by Keyleth’s father, to be of aid to her in her grief".[4] This initial character idea eventually morphed into Orym, his player character in Exandria Unlimited and Campaign Three.

Liam took part in the D&D Beyond Presidential Campaign, a recurring sponsorship segment created by Sam Riegel.

Liam began his career in theater before moving on to voice acting in the early 2000s. He also branched out to voice directing, and has worked on several productions, like The Last of Us and Resident Evil 6. A lot of his work revolves around japanese anime dubbing, be it as a voice actor, voice director, or automated dialog replacement writer. One of his most well-known speaking roles is the character Gaara from Naruto.

Personal life[]

Liam is married to fellow voice actress Amy Kincaid. They have two children together, and owned a dog, Sprigg, who was named after the guest character of the same name.[5]

Liam has stated that D&D has helped him get through a rough patch in his life after he developed hyperacusis.[6]

  • He shares his middle name, Christopher, with Matt Mercer.
  • Liam is 5'11" tall.[7]
  • Liam ties Travis for most player characters at 18. He additionally played a non-DM non-player character Cinna Brightbow.
    • His most played class is Fighter, with four characters.
  • More of Liam O'Brien's player characters have died than any other cast member on Critical Role.
    • Six of the characters Liam has played across one-shots and the main campaigns have died. Five of them were beyond resurrection or within a game without resurrection rules at their final death.
  • Liam is the only member of the cast who has played two characters of the same family: Derrig and his son-in-law, Orym.
  • Critical Role is Liam's first "pure" game of Dungeons & Dragons. Before this, he was a Dungeon Master in his sophomore year of high school as well as a player, which, as he states, "is totally cheating."[8] He also ran a Rift game as well as a Cyberpunk game. After Critical Role became such a large part of Liam's life, he began running several D&D games for his children.[citation needed]
  • It is tradition for Liam to choose Sam Riegel's character's race and class at the beginning of each campaign, but his involvement ends there, so he doesn't have influence in potential multiclassing, transformations, or even second characters during the campaign.[9]
  • When asked who he'd pick if he could switch to any player character in Campaign One, Liam chose Scanlan Shorthalt.[10]
  • Liam has been praised more than once for being part (as his characters) of some of the most popular ships of Critical Role. However, when asked about how he perceived fan reactions about couple involving his characters, he explained he tried to focus only on the table and his own way of playing the character, to avoid getting influenced by external opinions that would alter his approach to a relationship in a campaign.[11]
  • After they played together as Orym and Opal, Liam and Aimee Carrero developed a private joke between themselves: since at one point the warlock pretended the Ashari fighter was her child Nancy,[12] now both actors keep up the gig when speaking on social media, with Aimee acting like a mother and Liam responding accordingly.
  • He GMs a Ravenloft campaign for his daughter and her friends, and has explained how their adventure started being adapted to be very family friendly (comparing it to The Nightmare Before Christmas), and as the players themselves grew up the tone became more serious and mature.[13]
  • Liam's chosen drink on his Between the Sheets interview was mulled wine.
  • Liam currently holds second place for attendance out of the main cast members for the main campaigns, just two episode appearances behind Marisha Ray. However, if one-shots are counted, he takes first place.
  • Liam's involvement in choosing fan art for the slideshows and official art books has earned him the title of "Art Dad" from the community.
  • Every Halloween, the cast of Critical Role dresses up in costume for one episode. Liam has dressed up as the Dread Pirate Roberts (2015), Tyriok Gadsworth (2016), the Sole Survivor from Fallout 4 (2017), Kylo Ren (2018), Gaara (2019), Astrid Becke (2020), Ashley Johnson (2021), Cyclops (2022), and Frodo (2023).
  • When asked which one of his Critical Role characters is his favorite, Liam said he was tempted to say Caleb Widogast because of the diversity of things he could do with magic and he loved it. However, Vax'ildan was really his heart, not only because he felt like an alter ego of Liam's, but also because everything started with the Vox Machina characters.[14]

  • In December 2012, Liam recorded audiobooks as the narrator for the Lost Legends books, a Dragonlance book series, with Sam as his Voice Director. This happened a little bit around their first home-game, making Liam's month "D&D 100% of the time".[15]
