Much like Ultraseven's Eye Slugger, the Ultra Bracelet was seen exploited by many enemies in the Ultra Series. Among them are:
- Alien Zelan: After successfully baiting Jack to duel his monster Plooma, Zelan took control of the bracelet via a remote controller after Jack turned it into Ultra Spark and tried to retrieve it. The weapon (as Ultra Spark) turned into a swarm of flying energy daggers and attacked Jack as the Ultra Warrior defended himself from his possessed weapon until it tried to constrict Jack to death. It wasn't long until MAT Captain tracked Alien Zelan and killed him with a shot, allowing Jack to regain control of the Ultra Bracelet and went away.
- Ace Killer: As part of the plan to eliminate Ultraman Ace, Yapool kidnapped four senior Ultra Brothers and had Ace Killer steal their powers (among them were Jack's Ultra Bracelet). Ace eventually managed to kill the robot assassin with his brothers' help and returned the bracelet back to Jack.
