Guys imagine if batman!Jason's(not necessarily injustice universe but in general) robin was one of these kids
Mar'i grayson.
Just imagine it i mean honesty I can see this happening in the future. I freaking loved redhood and the outlaws and I truly believe Kori wouldn't mind if mar'i became the robin to jasons batman. Obviously later on she switches to nightstar
Janet aka a bat grandkid from Batman: Lost #1 now obviously she's most likely tims kid since Janet was his mom's name in New earth continuity. Now I for one loved the dynamic that tim and Jason had during the new 52 batbooks and just the 20teens in general and considering that, I can just see Jason as batman Taking Janet on as a protégé because honestly if we look back at new 52 tim who said and I quote
"you came back to life, jason. After you were murdered. That was alot to digest. I get it. Maybe we'll all get it someday."
I don't think tim would have that much of a issue with Jason training his daughter.
Same as above i can totally see one of these kids being the robin to their uncle Jason's batman! One of the others can be batling or kid bat and just to mix it up maybe the next spoiler can be one of the boys
Honestly I can see Jake totally being robin after his sister then being batlad or something.
Honestly i can see John as being either robin or batlad/batboy. Yes I know dick in batman beyond hates the idea of his non superpowered kid being in the hero life but damn it Barbara would so be for it(shut up im using logic here based on Barbara interaction with the next person on this list!)
This woman Elainna Grayson if given the chance she would have totally been robin if not for her dads overprotectiveness. I hope they continue to use her in the batman beyond comics especially since they set up Barbara being her mentor
Athanasia Wayne
Oh lord imagine this lol i wanted this so bad in injustice so I decided that in my AU THIS WILL HAPPEN! Athanasia will be the robin to her big bro jasons batman! I HAVE SPOKEN!
