Author's note:

Okay, I am gonna have to go over the list of characters before we get to the main story.

Titans Members:

Prince Artur To'Mas Atlan/Arthur "AJ" Curry Jr./Aqualad II

Connor Hawke/Green Arrow II

Lian Nguyen Harper/Speedy II

Jonathan "Jonny" Samuel Kent/Superboy II

Don Allen/Tornado Boy

Dawn Allen/Tornado Girl

Damian Al Ghul - Wayne/Robin IV

Jennifer Pierce/Lightning

Mar'i/Mary Anders/Nightstar

Martin Jordan II/Green Lantern

Kiyera Hol/Hawkgirl

From my perspective, the fifth season should be called Young Justice Titans, since no other teams were named that for now. This version of the Titans does not associate with the Justice League, but continues to aid them under their own terms as a means for independence, unlike the Team, it the Outsiders.

Plus it was too overkill that in the original comics for plots that such kids like Lian Harper, and Arthur Jr. had their lives taken too soon that they could've ended up heroes like their own parents. But even if Lian was revived in a new timeline, I think there should be more to her development in her character.

Seeing those next generation in one place in Season 3 of Young Justice indicates that they will have a future to become the heroes who will battle Apokolips in a later timeline. Meaning that those kids will gather to become a unity that surpasses the heroes in the Silver Age.
