From the annals of "Oh, What Might've Been" comes this doozy, courtesy of Brian Michael Bendis: art from Phil Jimenez 's pitch for a Justice League/Transformers crossover that, for some reason, never came about.
"Oh, what an epic that would have been," Jimenez wrote last night on Twitter, saying to one follower, "You missed out on Wonder Woman's invisible jet becoming a very cool Transformer." You can get a peek of that in the image above, along with an enormous Bat-former and, perhaps best of all, Optimus Prime as a Green Lantern. (He added this morning, "Giving credit where credit is due: the idea for Optimus Prime as a GL was none other than [IDW Publishing Editor-in-Chief Chris Ryall's]."
Jimenez also dusted off another piece of art featuring Prime wielding his power ring and Megatron clutching Superman's tattered cape, which you can see below. Hopefully the artist will offer more details about the pitch, and why it never went anywhere.
