Jade tried to rescue her brother from the Starheart's control, but both brother and sister fused together and formed a hybrid with the powers of both Jade and Obsidian, all the while in the Starheart's control. Together, the siblings attacked the Justice League and the Justice Society until Jade is contacted by the Entity. Jade resisted the Starheart's control and tried to balance the darkness inside of both of them. Jade and Obsidian are eventually separated by the Entity so Jade could complete her task, however Obsidian became paranoid and tried to force Jade to fuse once again with him. Jade managed to prevent the fusion but Obsidian was restrained by Kyle in a green bubble and taken far away from Jade. Jade managed to restore her father's Starheart, which was revealed to be the unidentified threat. In the end Jade is reunited with her father who returns to normal but she cannot approach her brother or vice versa or both of them would eventually fuse once again into the hybrid and risk releasing the Starheart.
