[post_page_title]Audrey Marie Anderson as Lyla Michaels[/post_page_title]
Lyla Michaels is the director of the Advanced Research Group United Support, also known as A.R.G.U.S. She is also the wife of John Diggle, an important member of Team Arrow and a big part of the Arrowverse. We first see Lyla Michaels (who has the codename Harbinger) in The Flash in Season 2, however, this character has been in Arrow since Season 1 back in 2013, so fans of the whole DC universe will know her well.
