Don't have to know anything about the show. I changed the concept up a little and made it in the future... honestly a new spin on Impulse could work but I'd rather a legacy from a deceased hero be filled. Not saying somebody should become the new Green Arrow... you could, but anybody could say that [insert hero or villain] is dead and that your character is the new character filling their boots figuratively and literally. 

In the classic Young Justice comic Impulse had a rivalry/respect for the seasoned hero the Ray because he flew at lightspeeds. Maybe you could do the Ray and just change him up? Did you know the Flash after the 80's Crisis was supposed to have light based powers of some kind and the Flash was supposed to be in the same context as "Flash of light"? More like the Ray eventually was a decade or so later... maybe you could do something with light/lightspeed be it running or flying and have the Flash keep tabs on your character? Lightray of the New Gods had similar powers as well as the enhanced physical attributes of the 'Gods... you could steal his name LOL

IDK man, I'm kinda making a mischievous character already and if it was Impulse with the usual personality they'd be quite a bit alike personality wise...

Booster Gold as someone's sponsor early on... I'm curious to see where this goes!
