Elizabeth Katz (born July 8, 1988) is an American cosplayer, actress, model and former porn star. After a brief career in the adult film industry under the pseudonym Risi Simms, Katz began cosplaying professionally after winning IGN’s Best Cosplay at WonderCon 2012. In 2012, she became a Twitch personality due to her extensive cosplay work, youtube channel, beauty and wit. In 2013, Katz undertook a crowdfunding effort to fund a cosplay outfit, raising US$4,690, starting from her original goal of US$650. This prompted a debate in some circles on the use of crowdfunding for cosplay. Playboy ranked Katz as the fifth sexiest cosplayer in 2014. FHM ranked her as the fourth sexiest cosplayer in 2016. Katz has since featured prominently at many cons and other events. Katz has appeared in a number of Sam Macaroni's works and had over 1,000,000 Instagram followers as of December 2019. Liz Katz/Risi Simms enhanced her small, pert breasts to full D-cup sometime after leaving the adult film industry. Years active: 2007--2012, 2016--Present Performances Boy/girl: Blowjob
