Mr. Twister: I was prepared to be challenged by a superhero. I was not, however, expecting children.
Robin: We're not children!
Mr. Twister: Objectively, you are. Have you no adult supervision? I find your presence here quite disturbing.
Wally West: You brought your utility belt?
Dick Grayson: Never leave home without it. First thing Batman taught me.
Wally West: Right after don't go to the bathroom without it.
Wally West: [to M'gann] I'm Wally. See? I already trust you with my secret ID. Unlike Mr. Darkglasses over here. Batman's forbidden Boy Wonder from telling anyone his real name.
Robin: [Flying in M'Gann's ship] Incredible.
Wally West: She sure is... I-I mean the ship. Which like all ships is a she.
Robin: Fast with the speed, not so much with his mouth.
Wally West: DUDE!
Dick Grayson: [after M'Gann drops a boulder on Mr. Twister] Don't know how things are done on Mars, but on Earth we don't EXECUTE our captives!
M'gann M'orzz: You said you trust me.
[Lifts the boulder to reveal an android]
M'gann M'orzz: That's why I couldn't read his mind.
Wally West: Cool! Souvenir.
Red Tornado: Mission assignments are the Batman's responsiblity.
Dick Grayson: But it's been over a week and nothing...
Red Tornado: You'll be tested soon enough. For the time being, simply enjoy each other's company.
Kaldur'ahm: This team is not a social club.
Red Tornado: No. But I am told social interaction is an important team-building excersize. Perhaps you can keep busy by familiarizing yourselves with the cave.
M'gann M'orzz: [Telepathically] Don't worry, Superboy. We'll find you an Earth name too.
Superboy: GET OUT OF MY HEAD!
M'gann M'orzz: [Telepathically] What's wrong? I- I don't understand. Everyone on Mars communicates telepathically.
Kaldur'ahm: M'Gann, stop! Things are different of Earth. Here, your powers are an extreme invasion of privacy!
Wally West: Besides, Cadmus's creepy little psychic genomes left a bad taste in his brain.
M'gann M'orzz: I-I didn't mean to...
Superboy: Just... stay... out!
Superboy: [to M'Gann] You tricked us into thinking Twister was Red Tornado.
Kaldur'ahm: She didn't do it on purpose.
Robin: It-it was a rookie mistake. We sholdn't have listened to her.
Wally West: You are pretty inexperienced. Hit the showers. We'll take it from here.
Superboy: Stay out of our way.
Wally West: Batman, Aquaman, Flash, they'd all have jumped right in to fix things.
Dick Grayson: Guess if we're going to have a babysitter, a heartless machine is exactly what we need.
Wally West: DUDE! Harsh!
Red Tornado: And inaccurate. I have a heart. Carbon-steel alloy. I also have excellent hearing.
Dick Grayson: Right. I'll strive to be... more accurate.
Kaldur'ahm: And respectful.
Brick: [to Speedy] You again? I'm starting to get insulted. Green Arrow's not messing up my operation.
Robin: So, Speedy, you in?
Speedy: Pass. I'm done letting Arrow and the League tell me what to do. I don't need a babysiter or a clubhouse to hang out with the other kids. Your Junior Justice League is a joke. Something to keep you busy and in your place. I don't want any part of it!
