Teen Titans or Damian's generation (4th Generation). If they were characters at his own age range.
- Damian Wayne (Robin V)
- Wallace Daniel West (Kid Flash III - I just gave him a middle name
)
- Emiko Queen (Speedy?)
- Maxine Baker (Animal Girl)
- Maxine Hunkle (Cyclone)
- Lagoon Boy
- Jakeem Thunder (Johnny Thunderbolt has a great-grandson so it could be him)
- Secret? (She's not being used that much; also if DC ever decide to rebirth 'Young Justice', I doubt she would be on the main roster because i think they are going with a line up which is similar to the TV Line up: Red Robin, Superboy, Wonder Girl, Impulse, Aqualad, Miss Martian and Emiko/Arrowette/Speedy/Tigress)
Maybe grab some characters from the YJ animated series.
- Tye Longshadow
- Asami Koizumi
- Eduardo Durado
- The Wonder Twins (New variations of them, because their JLU incarnation are dead and JL 3000 was cancelled).
Others that could work with Damian's generation.
- Jon Kent (he's three years younger than Damian, I think)
- Darkfire
- Warlock’s Daughter (Minor character. Could work well with him)
- Son of The Fallen (Minor character. Saw him in one of the scans from the Pre-New 52 Teen Titans series)
- Equinox (She just disappeared after JLU)
- Empress (A character from the TJ comic series)
- Klarion
- August Heart (The new speedster that's going to appear in The Flash #2)
- A New Wonder Girl (Cassie can be called Olympia, since there is a new Superman and Kid Flash, and Kaldur is going to take the mantle of Aqualad and Emiko might take the mantle of Speedy.)
Longshots (All three were the children of the golden age heroes, so they could be teenagers trapped in the present - doubt they are going to appear because the JSA could be in their 20-30's)
- Jade
- Obsidian
- Jesse Quick
- Silver Scarab
- Rick Tyler
