Still: there are people dressed as MiniMates. MiniMates!
Spotted on the Distractotron YouTube Channel, this video parades hundreds of DC Comics characters in front of your eyes for a glorious spectacle that's over here minutes. I especially love how you can see clusters of the same characters in various parts of the video. "Let's get all the Nightwings over there and the Poison Ivys to the left a little, ok, guys?"
Dean Cain—who once played the Last Son of Krypton in the late Lois & Clark show—came dressed as himself. Helped some folks declare their love for each other, according to the comments. That's… super.
