characters as superheroes
They're all pretty great, but I think my favorite one has Pierce as Ted Kord Blue Beetle, Abed as Martian Manhunter, Jeff as Booster Gold, and Troy as Green Lantern. I agree with one of the commenters - I could actually hear that dialogue in my head in the actors' voices.
The second one - with Britta as Batgirl and Annie as Batwoman - seems like the roles should be reversed, at least based on the characters' respective ages.
I also like the recurring joke that Troy wanted to be, or should've shown up as, Spider-Man. Although I am looking forward to seeing Andrew Garfield as Peter Parker, I still kind of wish Donald Glover had been cast as Spider-Man...
