Martian Manhunter
With Supergirl having made her way from CBS to The CW, she brought along Martian Manhunter for the ride. Within the Arrowverse, he took on the persona of Hank Henshaw, masking his true identity as the Martian shapeshifter by the name of J’onn J’onzz.
Martian Manhunter has sworn to protect planet Earth, preventing it from facing the same fate that befell upon his home planet Mars. His carefulness and constant alertness that makes him a force to be reckoned with, which is part of the reason why he serves as the Justice League’s number one asset in the comics in case Superman goes berserk. Now matter how powerful the entity, chances are J’onn has a plan to dispose of it.
He most definitely deserves a spin-off of his own, delving a little deeper into the alien realm Legends of Tomorrow briefly touched upon. Besides that, J’onn is a rich enough character to spin an entire story line around. Seeing how Supergirl recently introduced Miss Martian, this merely adds to the potential route a Martian Manhunter solo series could take.
