A few days ago Nerdist news broke out with the new Titans Roster (totally contradicts my fancast roster but still would love to see Superboy sometime join the team in season 1. Artemis, Aqualad (Kaldar'Ahm) and Miss Martian in season 2)....
NIGHTWING (DICK GRAYSON): Recently getting over the partnership with Batman. Love to see Batman Flashbacks and to see the killing joke be the main reason why Dick leaves Bruce's side. He is also private detective in Boston. Okay ppl i am tired of seeing ppl put that he is a cop. Wrong... He is a Private Detective which means Private Investigator, which makes more sense than him being a cop. He starts off as Robin but will eventually don the Nightwing costume.
Starfire: Tamarian princess who in the comics becomes a great part of the core team of the Titans. Not alot of info on her for the Titans show except she shows at the end of the pilot episode with this other Titans member.
Raven: A half human, a half demon superhero. Daughter of interdimensional demon Trigon. She was another core member of the team. She will be going with the alter ego Rachel Roth that was made during Geoff Johns run in the 2000s.
Barbara Gordon: Formally known as Batgirl, commissioner Gordon's daughter, and the ex girlfriend to Nightwing (Dick Grayson). She will be wheelchair bound and the team's computer hacker. May result in a love triangle with Dick and Starfire. Not sure about this, still holding out for Artemis to be in this show whether its Thea Queen or Artemis Crock to be involved with Dick after Starfire. Love to see the killing joke in BG's flashback.
Hawk and Dove: No not the brothets version. Its the male and female new 52 version. Hawk an agent of Chaos and Dove an agent of Order. Interesting choice for the team. To be honest i have Dove dying in season 3 of the show and season 4 Hawk becoming the villian.
In summary I think this roster is interchangeable and love to see these characters later added to the roster....
Beast Boy- Dylan O'Brien
Like to see his origin start around in season 3 and linked to Miss Martian in someway. Like how they did it in YJ but different. And become full team member in season 4.
Robin (eventually Red Robin) (Tim Drake)
Drake and Grayson run into each in season 4 and becomes a major recurring character of the Titans team in season 5. Eventually may form his own team.
Zatanna Zatara- Lindsey Morgan
Zatanna is more of a character that will pop in on the team from time to time. Either cuz Titans ask for her help or vice versa.
Bumble Bee (Karen Beecher)- Amber Stevens
See her become a reccurring character with her boyfriend Malcom AKA Gaurdian in season 5 and pop in from time to time past season 5.
Guardian (Malcolm Duncan)- Sinqua Walls
He is in the show as a recurring character in season 5 and pops in from time to time.
Blue Beetle (Jaime Reyes)- Tyler Posey
Blue Beetle appears towards the end of season 4 and becomes a huge part of the team from season 5 and on.
Jericho (Joseph Wilson)- Mark Lawson
Entering around end of season 5 to help Titans vs Deathstroke but eventually becomes evil and dies in season 6
Ravager (Rose Wilson)- Leven Rambin or Claire Holt
Rose appears in Season 7 after her brother's death to help them and get to deathstroke. Becomes a nice recurring character.
Tulah- Kelley Rose Missal
Tulah comes in around season 3 and then in season 5 and helps the team in the war with Deathstroke and his allies. Pops in from time to time from season 6 and on.
Wondergirl (Cassie Sandmark)- Skyler Samuels
Major recurring character in season 5 and on.
Robin (Damian Wayne)- Zachary Gordon
Season 5 appearance as part of his grandfather's (Ra's Al Ghul) League of Assassins but is rescued from death by Deathstroke by Nightwing and Robin (Tim Drake). Eventually time passes and Batman sends his son Damian to learn from Nightwing how to be a better hero, a better person towards the end of season 7 and on.
Static Shock (Virgil Hawkins)- Leon Thomas III
Season 4 character pops in from time to time. Helps majorly in season 5. Pops in from time to time again after season 5.
Impulse (Bart Allen)- Connor Paolo
Appears in season 8 and on to help the team in prevent a certain event from happening.
Wingette (Cheyenne Freemont)- Chloe Grace Moretz or Mackenzie Roseman
Changing up her character and not a superpower being and not Nightwing's love interest. In this show she is Dick Grayson's long lost sister! Have her appear in Season 9 after Dick Grayson's supposed death. Finds out he was Nightwing the superhero and tries to carry on the legacy as Wingette. Gets help from his girlfriend Artemis (Hoping for Artemis in the show and as Nighwing's as they say his one true love and not Starfire.)
