Now for those of you who don't know who hush is he is a DC villain [mainly batman's villain]. For those who don't know who he is here are in origins.
Now that you know who he is, you should now know why he might be coming to the big screen or little screen [TV universe].
Now arrow has taken many villains and heroes into the show. Some of which aren't even his in the comics [deathstroke]. And rumors are we may see Hush.
1. They said Hush deserves to be seen more.
2. More villains are showing up.
3. He could be introduced as a young friend of Oliver [like batman].
THE SPIN OFF SERIES AND TEEN TITANS
He could show up in these series because..
1. Damian Wayne will be in teen titans and in the comics Hush would fight Damian.
2. The spin off series is featuring so many combined heroes and villains [captain cold and captain atom]. They easily have room for Hush.
4. Hush also is known for taking peoples faces he could pretend to be one of the titans or spin off heroes to infiltrate and begin a plan.
THE SUICIDE SQUAD AND NEW DC MOVIES [BATMAN]
Now this seems the most likely to happen..
1. The suicide squad is featuring so many villains that in the comics aren't even in the squad [Joker]. Could Hush be in the squad or even better the villain of the squad.
2.He is a villain of Batman he could easily be in the solo batman movie which is rumored to happen.
3. We have seen the same old villains of batman in the movies it would be a good and fresh idea to see a new one.
4. With the Justice league movies coming he could be the villain of those movies or be apart of a team of villains in those movies [league of doom].
