Jack first appears with his artificial brothers alongside Darklops Zero, confronting Ultraman Zero and the alternate ZAP Spacy crew. However, Zero managed to escape from them after he destroyed Imitation Jack and Imitation Zoffy.

Many Imitation Jacks were seen being ready for transport. However, Darklops Zero turned on the Salome and started to destroy the other robots.
Powers and Abilities
- Ultra Lance: Based on Ultraman Jack's Ultra Lance. A lance that can destroy monster in one hit. It appears to be weaker than its original counterpart.
- Unlike his counterpart, he only wields an Ultra Lance than an Ultra Bracelet.
- When Robot Zoffy was seen destroyed, an Ultra Lance was seen impaled to his body. Since the Robot Jack had his Ultra Lance destroyed earlier by Zero's Emerium Slash, it could be noted that either the robot has the ability to generate another Ultra Lance or the first Robot Jack was destroyed, and a second one was sent to destroy Zero who also brought another Ultra Lance.
