6. Booster Gold
There’s been talk of a Booster Gold solo series on SyFy, but Geoff Johns has already brought this character to the small screen once before (in Smallville), so don’t be too surprised if he turns up in The Flash at some point! Originally depicted as a glory-seeking showboat from the future, using knowledge of historical events and futuristic technology to stage high-publicity heroics, there turns out to be a lot more than just that to Booster and he even becomes a pivotal member of the Justice League further down the line. If time-travel does indeed play a role in this series thank to characters like Reverse-Flash and Kid-Flash, then someone like Booster would fit right in. It’s up to the showrunners to differentiate him from past versions of course…
