Those amazing times where Clark & Lois had cameos in other universes, out of DC's universe:
"Excalibur's New York Adventure," Excalibur #8 (Marvel, 05/89)
"21st Century Boy," The Ultimates #3 (Marvel, 05/2002)
This time it's Clark, Lois and Jimmy out for a night of glamor and investigative journalism, this time tracking down the Ultimate Marvel (Earth-1610, for those who care about such things) version of Tony Stark for an interview.
More appeareances from Clark & Lois outside the DC universe:
"Krobaa, the Abyss That Walked," Venom: Seed of Darkness Flashback -1 (Marvel, 07/97)
"Untitled," Youngblood #3 (Image, 08/92)
"So LINE is this really cool app that you can use to send messages and all that good stuff but, one of the cool features is the ability to buy stickers and use them with your friends. They recently added these Superman stickers and I thought it would be fun to show them." (We have Supes & Lois stickers, yay!!!)
