R.L. Jackson Observatory

The R.L. Jackson Observatory is a location in The Powerpuff Girls, the location where Mojo Jojo had been hiding for ten years since the incident at the Devon Group.

Season 1
As part of the agreement, Reese Baum agreed to take John Utonium to meet the higher power. During the summing of the demon at Millennium Park, Reese brought Utonium to the observatory and led him to a room on the 10th floor, where he was shocked to see Mojo Jojo, alive but hooked up to life support. Utonium was also surprised to find that Reese was betraying him, but Kathleen Keane had luckily followed them and killed her before she could kill Utonium.

Season 2
Following Reese's death, John Utonium and Kathleen Keane continued to visit the observatory. It was there where Utonium realized that Mojo was wearing a helmet that Reese had been working on at the Devon Group ten years prior, and that since Reese did not have the Chemical X on her when she died, it was likely in the possession of her former scientist, Sudhir Bachchan. Soon after, Kathleen visited alone, when she was surprised by [[Malcolm Jules who, on behalf of Mojo, conformed Sudhir was the Chemical X and offered to help track him down.
