Ralph Dibny played a central role in the events of "Identity Crisis", with the main arc of the series revolving around the DC Universe's response to the murder of Sue Dibny. The healthy, stable relationship between Ralph and Sue, and the events that led to and resulted from her death, were used as primary narrative devices throughout the series for examining the respective personal relationships of other JLA and JSA members (and to a lesser extent, members of the supervillain community).
