Unlike many of his other Prelates, Dark Enerjak kept Prelate-JS out of previous battles with the resistance as he wanted to save her for a "special occasion." After Enerjak destroyed the secret base of Freedom Fighters, he summoned JS to fight alongside the rest of the Chaotix Prelates and commemorate the rebels' final stand, which caused much rage in her own daughter Jani-Ca. However this did nothing to deter JS from leaping into battle at her, forcing Jani-Ca to fight her with the Sword of Acorns. (SU:#26)
- When Prelate-JS is formed from her core, she makes a sound that is a shortened version of Julie-Su's name: "JUSU!"
- Prelate-JS is very similar in appearance to the fully armored Shade the Echidna from Sonic Chronicles: The Dark Brotherhood. This may be a nod to the fan theory that Shade was in fact based on Julie-Su's character.
