8. Kid Flash


Bart Allen hails from the distant future and is the grandson of Barry Allen. Originally called Impulse and later Kid Flash, the character’s origin has been altered as a result of “The New 52” reboot (seemingly removing any familial connections to The Flash), thereby giving the team behind the series a lot of options to work with should they choose to bring him to life on the small screen. The current iteration of Kid Flash is unsure of his origins and simply assumes that they’re somehow connected to the Speed Force, and having him mysteriously arrive in Central City could prove an interesting dilemma for Barry! Still, with Grant Gustin already a fairly youthful version of The Flash, it probably wouldn’t hurt to wait a few seasons before introducing this particular hero!
