Grant Morrison, whose pre-Vertigo work on "Animal Man" and "Doom Patrol" was similarly retroactively branded as "Vertigo" when collected, also wrote two issues of "Hellblazer" pre-Vertigo, which are collected in a 2005 trade paperback. Wrote three volumes of "The Invisibles" between 1994 and 2000. In addition, they had produced a number of miniseries including "Sebastian O" (1993), the Doom Patrol spin-off "Flex Mentallo" (1996), "Seaguy" (2004), "Vimanarama" (2005), "We3" (2004–2005) and "Joe The Barbarian" (2010) as well as the longer miniseries "The Filth" (2002–2003). They collaborated with writer Mark Millar on five issues of "Swamp Thing" in 1994, produced two one-shots — "The Mystery Play" (1994) and "Kill Your Boyfriend" (1995) — and contributed to several anthologies.
