Owned and run by Jack Haly, the circus's star attraction were the Flying Graysons. Mob boss Zucco attempted to extort money from the circus, and when he failed, he murdered most of the Flying Graysons in a staged trapeze accidenton April 1st, 2006,
The fourth stop of the European tour proved just as troublesome as the others. He had a flu keeping a lot of his performers down, and because of a string of burglaries that coincided with the Circus's shows, Interpol agent King Faraday was nosing around the circus. Haly replaced the ill Carlo and his brother with the Daring Dangers, and the new group proved popular.
Before the show in Switzerland, the Dangers made it clear that they wanted to part ways with the circus, now that the real culprit behind the robberies was gone and everyone at the circus was in shape again. Haly knew full well that the youngest member, Dan Danger, was actually his old star Dick Grayson, and convinced him to do one last act.
