Jet Star was one of the founding members of the Fabulous Killjoys. He is played by My Chemical Romance (MCR) guitarist Ray Toro. Jet Star is most often seen wearing a black jacket with an American flag on the back, a lightning bolt gas helmet and sunglasses, though he has been portrayed in some media as wearing an eye patch rather than glasses.
He seems to be a poor shooter. This could be because he is missing an eye, although this seems to be an inconsistency.
- Fanon interpretations of the Killjoys often utilize information about the My Chemical Romance members to portray them to fill in backstory details that weren't mentioned in the videos, comics, or other supplementary material. As such, headcanons about Jet Star's background often are shared with Ray Toro.
