J4/Neo Jetman 4 is the codename of an unnamed member of the Neo-Jetman. He makes his first appearance saving the Jetman from Meteor BEM before it could finish them off. After Supreme Commander Akira Ichijou disbands the original Jetman, J4 and the other Neo-Jetmen aggressively threw them out of SkyCamp. When Meteor BEM infiltrates and begins to destroy SkyCamp, J4 and his teammates are overpowered, and were forced to take a last stand when Ichijou locks them and Aya in the same room. When the original Jetman join the fight, J4 and his team sacrifice their powers to give them their powers back, ultimately making peace with them and admitting they are the true Jetman.
