Molenaar was asked by publisher Rob van Bavel to take over the popular Dutch comic series 'Storm', following the death of the original artist Don Lawrence in 2003. Molenaar gave up his dayjob at the reproduction department of a technical office and has done the artwork for new stories in cooperation with colorist Jorg De Vos since 2006. The stories, written by Martin Lodewijk and later by De Vos, are first published in Eppo magazine and then in albums by Van Bavel's Don Lawrence Collection. In 2013, Molenaar also started a spin-off series starring the female character 'Roodhaar', for which the scripts are provided by none other than 'Conan the Barbarian' writer Roy Thomas.
