Fiction

2005 IDW continuity

...Unless, could Jhiaxus steal Starscream's power with a high five?

Jhiaxus donned the reactive armor to buy time for Shockwave's plan to come to fruition. When confronted with Metalhawk, Starscream, and Rattrap, Jhiaxus first demonstrated the armor's abilities by copying Metalhawk's arm-blades. Starscream fired upon Jhiaxus, only for the reactive armor to absorb the blast and transform into a duplicate of Starscream's new body. Black Planet Jhiaxus engaged Starscream in hand-to-hand combat, using copies of Starscream's built-in swords to keep him on the defensive. However, this proved to be the mad scientist's undoing, as Starscream had been unaware his new body even HAD swords up until this point. Starscream took the hint and deployed his own swords, impaling Jhiaxus through the reactive armor and killing him. ...And the Damage Done
