"If you click this button it will open the folds of all the heroes in our database." Jonn explain while he look at you with a nonchalant glare. But it's seems that he's trying to be at least a little friendly. "And if you click the red button it will show all the informations of the hero on the data base of the Justice Tower."

Jonn is clearly an alien and he doesn't care about hide it, he show his green skin and his red eyes all the time, except when he's on a mission where he need to disguise himself. That's why he has his name Martian Manhunter.

"That green button will show the actual localization of the heroes that are in a mission right now." Jonn explain, trying to sound a little more empathic, you're the new hero. And he read your mind of course... because of that he knows that your feeling out of place, so he's trying it act like humans and be kind with you. "You can press it, if you want."
