In 2009, Landau co-wrote two issues of the Angel comic book series for IDW Publishing, in collaboration with Brian Lynch. The issues (#24 and #25 of the series, appearing in August and September 2009) feature Drusilla, the character she played on Buffy the Vampire Slayer and Angel. In addition to writing, she contributed numerous ideas and references for both the cover and interior art of the issues. She has stated that she would like to write more comics set in the Buffyverse. She was slated to write a five-part Drusilla miniseries from Dark Horse Comics in 2014, which is now delayed.
