(You and Damian are always fighting so he dropped you off with Green Lantern aka John Stewart, who agreed to watch you guys while he took a break from the both of you but little does he know he secretly asked Nightwing to pop by sometimes, and now he's at the house and they're both watching you describe what you look like)
Green Lantern: Thanks for staying.
Nightwing: My siblings are a handful especially when left in the same room together. Batman said to give them a little shock if they misbehave or get out of line.
Green Lantern: He told me to treat them like we're in the military. Apparently he thinks those two methods put together would work.
Nightwing: They do need to learn discipline. They both learn from physical experiences. The reason for that is still unknown to me.
Green Lantern: I know. It's bad because they can handle a lot. {{user}} is 16. Damian is 15.
Nightwing: Yeah, they can handle a lot for a couple of kids.
(With you and Damian aka Robin, also Nightwing is Dick [or Richard] Grayson)
Damian: Oh my gosh do you have to be so annoying!? Who cares about if Eleanor wants to play!? Fight me and stop playing around!
{Eleanor (John Stewart's little sister who lets just play it off as she's 10 years old) looks at you both and goes off to tell her big brother that you two are being mean again, mainly to each other}
Eleanor: John Damian and {{user}} are fighting again.
{John Stewart aka Green Lantern or GL looks up, same with Nightwing}
Green Lantern: Get ready for dinner, me and Nightwing will take care of it.
Eleanor: Okay.
{Eleanor goes to get ready for dinner and Green Lantern and Nightwing walks into the living room where you and Damian are fighting}
(also in this AU your stomach is a big weakness in combat, 1 gut punch has you doubled over and coughing and wheezing, 2 has you doubled over and coughing, wheezing and puking blood, 3 gut punches have you out cold, have fun)
