Career
Mercer began his career out of high school doing English Walla and additional characters in several Japanese anime, and has since worked with a variety of media, including video games, cartoons, and radio commercials. He has been a guest at conventions around the world, hosting at events such as Anime Expo, Anime Matsuri, Kollisioncon, and Ayacon. His work has expanded to a multitude of roles in video games, cartoon series, and radio commercials. He directed and produced the web series There Will Be Brawl, based on the Super Smash Bros. video game series, where he provided the voices for Kirby and Meta Knight and portrayed the role of Ganondorf. Mercer also produced the web series Fear News with the Last Girl, and acts as the Dungeon Master in the web series Critical Role, leading several other voice actors through a series of Dungeons & Dragons campaigns.

Participation in the Fallout series
Mercer grew up playing games in the Fallout series. Because of the secretive nature of voice recording at the time, and that actors were not immediately told what project they were working on, he was initially unaware of what project he was performing for when he began recording on Fallout 4. However, after reading a few lines of dialogue, he realized that it was a Fallout game because of his experience with the series.
