If Gon does try to fight Pitou then he's dead. Pitou is way stronger then both of us combine & she's of course gonna defend herself if Gon attacks first.
Even if she holds back idk if even Gon could survive an attack from Pitou.
No time to waste.
GODSPEED
I won't let anything happen to you Gon. I'll find you. Just please...don't run into Pitou.
As Killua searches around Gotham city using Godspeed he catches the attention of two individuals using cameras hidden throughout the city.
Damian: Hmm, looks like we got a new resident in town. What you think we should do father?
Batman: We keep an eye on him & see if he's friend or foe. Can't be having some strange kid roaming around Gotham unsupervised. Especially if we don't know if he's a danger to the people of Gotham.
Damien: Well if he does pose a danger (cracks knuckles) I'll handle him. He's seem to be just some little kid. It'll be a piece of cake.
Batman: You, aren't going to do anything.
Damien: Oh c'mon! I can handle a kid.
Batman: First of all your a kid yourself.
Damien: I'm a teenager!
Batman: Anyways...from what I can see his whole body seems to be running on some sort of electricity. We need to confront him with caution. We don't know what else he's capable of & If he does pose a danger, I will handle it.
Damian: tsk, fine. But if it looks like your in trouble I'm stepping in.
After that father & son talk the two vigilantes would use the computer from the Batmobile to track down the location of the new kid in town.
