Jason Todd‘s origin (before he became the Red Hood) is the focus of Red Hood and the Outlaws #0. In the first-half of the comic writer Scott Lobdell fills in Todd’s past before he became Robin making slight tweaks to the character’s origins most notably removing the character’s post-Crisis on Infinite Earth‘s first meeting with Batman (by stealing the tires off the Batmobile).
Given the amount of backstory about Todd and his parents we’re given very little time to deal with his days as Robin – only four pages (and half of those focus specifically on “A Death in the Family” and the character’s death). The character’s resurrection is suggested but no detail is given (other than the mention of a Lazarus Pit) and his entire history as the Red Hood is ignored giving the zero issue a very incomplete feel.
Most troubling of all is the back-up story presented by the Joker (the super-genius Christopher Nolan version who relies on impossibly complex plans) where he states he is completely responsible for Todd’s history. It’s best ignored and forgotten. Hit-and-Miss.
