Captain Marvel the Super Nanny
The JL has seen how Marvel is with their sidekicks (read: kids) so, they ask if he can babysit them. So, if a JL member has a long term mission they will ask him to watch after them. What they don't expect is Marvel help them parent their children.
When Marvel agreed to watch Arsenal's daughter. Arsenal didn't expect Marvel to clean his house and give his daughter some new experiences. Marvel stayed and showed him how to do things that would help him understand his child and he couldn't be more thankful.
And Arsenal tells everyone about the improvements Marvel made in his and his child’s life. Now Marvel is being invited to the parents club as the nanny.
When Batman asked Marvel to watch his kids he was expected to watch the young Robin or maybe Red Robin, not all of them. See Alfred is out of town and Batman has an outer space mission. He’s heard great things and decided to test him with his kids permission (read: Alfred forced him to ask the kids and they agreed)
Batman comes home expecting Marvel to have given up, instead he see him talking to Jason about Greek mythology; Cass is on his shoulders while he takes a walk in the gardens as “it’s a waste to not admire the gardens that Mr. Alfred, sir worked so hard on”. He can see Damian playing chess with Barbara, barely any weapons near Damian. Dick having a picnic with Duke and Steph while Tim sleeps on the blanket.
They all look at peace. Marvel spots him and the bat kids asks him to stay forever, Marvel refused (Bats didn’t know if he should thank the gods for that). And now has a notebook that Marvel made and gave him to help him grow closer with his children. Alfred now has his number and has invited him to many dinners which marvel’s refused (read; Alfred knows he’s Billy and Billy isn’t trying to be adopted by the Wayne family)
