In the aftermath of Terror Titans #6, Clock King is on the run and the remaining 3 (Dreadbolt, Persuader, and Copperhead) plan revenge against him....I think that there should be new members for this vendetta. And for this new mini-series...there should be New Terror Titans vs. the old Terror Titans.
The Trident mantle has been used by 4 people, 2 of which are dead....a new person would make an interesting collection for the New Terror Titans. How about a younger brother of the Sammy Jaye, a Trident died in New Teen Titans Vol. 1 #33.
A major villain to Cassie/Wonder Girl, but lesser known in the super-villain team community. This Silver Swan needs to be with people of her own age.
I know that he's a hero, but it is revealed that he is a robot created by the original Toyman...thus making him a Trojan Horse in the superhero community and a threat.
His son, not the 'undead' one, might be a good asset to the team...but maybe too smart for this crowd.
The son of Dr. Sivana.
The daughter of Dr. Sivana.
The niece of Lex Luthor.
The daughter of Lex Luthor and Contessa Erica Del Portenza. She was given special abilities by Brainiac, and aged her into a young woman.
Despite being an infant again, she could revisit her experience again. Another powerful candidate.
Despite his death, Inertia/Kid Zoom could be re-cloned (like how Conner/Superman and Bart/Flash from Titans Tomorrow were re-cloned by Tim/Batman). The Thawne legacy needs to live on and Super-speed is something the Terror Titans don't have.
The daughter of Madame Rouge, a shapeshifter for The Brotherhood of Evil (both the mother and daughter)...she could be the Beast Boy of the group.
Seven generations of the high priest of Trigon, and yet Brother Blood lives on. He's too powerful, but he can be the Raven of the group.
The 'son' of Amazo. Was destroyed....but maybe be rebuild. Also too powerful.
Their have been 4 people who took up the Red Panzer mantle. The third was killed by Damien Darhk and the fourth was a random guy named Justin from the HIVE. The last two were Titans foes....people should remember the Red Panzer.
Son of Yellow Wasp, an enemy of Wildcat and the JSA.
The daughter of the Dragon King.
The daughter of the second Dr. Polaris. She appears human, but I figure that a power-suit and a name would welcome her with open arms.
The sidekick to Catwoman and a member of the Falcone (crime) family.
The daughter of Mirror Master Evan McCuloch.
Despite this new one being an undercover HONG KONG policewoman, their needs to be a new villainess LYNX.
A clone of Supergirl gone wrong. Too powerful.
The son of The Silver Fog.
There's not much information about her, and I am not entirely sure if she is teenager or is related to the original Crazy Quilt (Paul Dekker). But she does the name to carry on.
The son of Toyman. (Wonder how Hiro Okamura will react.)
According to her history, she is the daughter of a mercenary named Wavelength. Now she calls herself Wavelength II (before/after killing her own father).
Ever since her appearance in Geoff Johns' Titans East story-arc, I had my doubts if she really was the daughter of one of Batman's greatest foe....THE RIDLLER, or some crazed fan (like Duela Dent/The "Joker's" Daughter, who was later revealed to be the daughter of an alternate and heroic version of the Joker.). But thanks to Batman #705, it has been acknowledge that she truly is Riddler's baby girl.
