I have Kitten shouting off the names of the various Justice Leaguers during the main titles to the cartoon.

“Look! They’re shadows! Ooooh! Batman! Wunnah Woman! Geen Lanern!” Pause. “Supuhman! Marrin Mannunnuh!” (Yes, she actually decently syllabifies “Martian Manhunter.”) “Oooh, Running Man!” (That’s “Flash,” to all of you.)
She hasn’t quite remembered Hawkgirl’s name consistently, though she recognizes her as Mommy’s Favorite.
More odd is her insistence on identifying the JL as “bad guys.” I don’t know if she misunderstands “bad guys,” or misunderstands what’s going on, or is just being self-amusedly contrary.
(For your bit of JL trivia today, here’s an earlier concept pic of the team for animation. Some obvious differences include GL’s costume and mask, HG’s gloves, MM’s appearance, and the use of the full JLA name.)
My little Katherine, age two and a few months, does something very similar with identifying the Justice Leaguers during the opening credits, but there’s one difference. She looks at Wonder Woman and shouts “Mommy!”
I’m pretty happy about that, as I’m sure you can imagine.
Now that’s cool.
