Done in Photoshop. My original size is 4500 x 1238 but I've uploaded a 2000 by 550 for the contest.
So: Superman from Action Comics #1 Aquaman from Aquaman #1 Wonder Woman from All Star Comics #8 Batman from Batman The Flash from Flash Comics Green Lantern from Green Lantern Sinestro from Green Lantern Mr. Freeze from Batman #121 Black Manta from Aquaman #35 The Joker from Batman #1 Doomsday from The Man of Steel #17 Poision Ivy from Batman #181
Phew...I'm finally done! Okay, so here we have Batman and Robin, (Who are from the DC universe.) as well as happy go lucky Starfire! (Who is from the 2003 TV series Teen Titans.) Teen Titans the original comic is from the DC universe, so I hope that the fact Starfire was in the new 2013 TV series of Teen Titans counts. In any case Robin is introducing Starfire to Batman, and...Batman's a little confused as to why Robin would date an Alien...But oh well! XD!
I also included the bat signal, as well as the one for Teen Titans! Well, at least...I THINK they had a signal...If not, then let this be the first! ^_^
(PS if no one can tell...The thing Batman is holding is his grappling hook, which is shaped like a bat.)
