Here comes how I headcanon the Batkids’ legacy (centering on the main Batfamily, I’ll make an extended version afterwards if you want ^^) through the ages and the titles they wear, first in canon then into their future!
Starring the team by oldest to youngest instead of by appearance :)
1) Barbara Gordon
Batgirl > Oracle > Mayor of Gotham
- Batgirl (at 18 when she makes her own path into vigilantism then teams-up with the orginal Dynamic Duo).
- Oracle (after the Joker shot her while, as an adult in her early thirties, she distanced from vigilantism and was wearing her Batgirl uniform only occasionally).
- Mayor of Gotham (she gives her ‘Oracle’ title to a reformed Edward Nygma who fully joined the Batfamily and dedicates herself to politics the official way since then, until her election as the new Mayor).

2) Dick Grayson
Robin > Nightwing > Batman > Nightwing > Retired
- Robin (at 11 after Bruce took him under his wing).
- Nightwing (the disco suit version at 18 after he quit, then the black and blue classical one after Barbara became Oracle).
- Batman (during the transition period over which Bruce was presumed dead).
- Nightwing (after Bruce returned).
- Retired (after Barbara and him married and he decided to fully dedicate himself to being a husband, a father and Babs’ main support over her political campaign).

3) Jason Todd
Robin > League of Assassins soldier > Red Hood
- Robin (at 10 after Bruce took him in and up to 16 when he was murdered by the Joker).
- League of Assassins soldier (up to his early twenties when he lived with Talia al Ghul and followed her training).
- Red Hood (first a villain when he returns to Gotham, then an antihero who progressively grows closer to the Batfamily. He keeps his Red Hood title up to his old days).

4) Cassandra Cain
Batgirl > Black Bat > Batman
- Batgirl (at 16 when she arrives in Gotham and after Barbara then Bruce and Tim took her in and considered her a true ally then a family member - she keeps her title until she gives it to Stephanie when thinking Bruce has died and she doesn’t want to fight for him anymore).
- Black Bat (once she returns to Gotham after living a couple years in Hong Kong away from the bats-and-birds).
- Batman (when Bruce solemnly hands over to her his cape and cowl, he chooses her as his rightful heir).

5) Tim Drake
Robin > Red Robin > Phoenix > Dark Phoenix
- Robin (at 13 after he stalked Bruce and until they cross paths, less than six months after Jason’s death).
- Red Robin (after he was forced to quit for a short period when his father found out about his activities and after Stephanie’s death, he couldn’t take back his old costume so he upgraded his outfit and his name along the way).
- Phoenix (over his mid-twenties when he decided to make a name for himself and take a chance into the ‘other side’ of the fight).
- Dark Phoenix (a nickname given by the press he ended up adopting after his team and him killed the next generation of Batman and Superman, aka Cassandra and Kon-El, what signed his definitive tipping point).

6) Stephanie Brown
Spoiler > Robin > Spoiler > Batgirl > Nightwing > Batman
- Spoiler (at 13 to frame her dad and spoil his plans before she bonded with Robin!Tim ; she takes nearly eight months off the Game to handle her pregnancy at 15 and its aftermath, needing time to recover after putting her baby up to adoption, then resumes the fight and meets Batgirl!Cassandra plus Oracle!Barbara).
- Robin (at 17 when Bruce finally takes her in).
- Spoiler (after Bruce fires her, leading to her ‘death’ and her spending nearly two years far from Gotham, in Kenya to recover with Leslie Thompkins. She returns at 19 wearing her original alias).
- Batgirl (at 19 when Cassandra abandons the title and she takes up the mantle for ten years to come).
- Nightwing (at 31, after two years off the the game to welcome her daughter Taylor ; she passed the Batgirl mantle to her apprentice Nell Little during her pregnancy).
- Batman (the one she never wanted to take up, but endorsed after Cassandra’s death to carry on the legacy).
