After the cancellation of Devil Dinosaur, the character's appearances were relegated to one-shot comics, cameos, and supporting roles in other series.

Some have followed Kirby's lead and portrayed the character as being from the prehistoric past of the main Marvel continuity (sometimes referred to as "Earth-616"), while others have depicted Devil as hailing from either an alien planet or an alternate reality Earth.

Exposure to the Killer-Folk's fire activated a mutation in the dinosaur which gave him powers greater than others of his species and turned his skin red.

[10] Devil's early adventures on his home world include encounters with extraterrestrials and a brief teleportation to modern day Earth.

While there, he briefly unites with Moon-Boy and Devil against a common foe before being pulled back to the main Marvel continuity.

During his time with the Fallen Angels, Devil Dinosaur accidentally kills "Don", the super-intelligent mutant lobster on the team by stepping on him.

[13] After their stint with the Fallen Angels, the duo's life back on Dinosaur World is interrupted numerous times by events occurring in the main Marvel continuity: Some time later, the sorceress Jennifer Kale, in an attempt to return Howard the Duck to his homeworld, inadvertently teleports Devil Dinosaur and Moon-Boy into her New York apartment.

Leaving the Savage Land without the permission of Ka-Zar and building an army of reanimated dinosaurs, Stegron marched across the U.S. attacking S.H.I.E.L.D.

The group discovered the motive behind Stegron's plan and, though he was arrested all the same, Reptil smuggled Moon-Boy back to the Savage Land, where he was reunited with his companion.

Lunella Lafeyette later obtains the Nightstone, identifies it as a Kree Omni-Wave Projector, and intends to use it to stop her latent Inhuman genes from activating.

She comes into conflict with Amadeus Cho / Totally Awesome Hulk and the Killer Folk before being caught in a cloud of Terrigen Mist and enveloped in a cocoon as her body mutates.

Lunella was at first relieved she had not changed physically, but was dismayed to learn her Inhuman power caused her consciousness and that of Devil Dinosaur's to switch.

Devil Dinosaur proceeded to make her even more ostracized at school due to freaking out in class and attacking other students whilst Lunella rampaged through the city.

[35] Devil Dinosaur and Moon Girl's next opponent came in the form of Kid Kree - a misunderstood Kree boy who had failed to enter the academy twice, who sought to capture an Inhuman to impress his father and make a name for himself on Earth as Captain Marvel had - who disguised himself as a new student, Marvin Ellis, in Lunella's class.

After consulting experts, Moon Girl, Hulk and Devil Dinosaur encounter Mole Man, who was attacking the city with a group of monsters.

Meanwhile, Doctor Doom is surprised to discover that Moon Girl is considered the smartest person on Earth and vows to prove himself superior.

While tracing Doom's location, Moon Girl and Devil Dinosaur arrive at the Sanctum Sanctorum and are found by Doctor Strange.

[40] Arriving at an abandoned mall, Moon Girl reengineers a Cerebro helmet with the Omni-Wave Projector to locate Doom, only for her and the X-Men to travel back to the 1980s.

She then encounters an army of Doombots, along with Thing, Hulk, Ms. Marvel, Ironheart, Doctor Strange, Kid Kree and the Killer Folk, who went to her aid after being recruited by Lunella.

[42] Lunella then receives a call for help from an alien girl named Illa and, after building a spaceship, goes to space with Devil and crash land on a moon.

Moon Girl and Devil manage to find Ego the Living Planet and reunite him with Illa, while the Doombot discovers that the Lunella robot is acting independently.

[volume & issue needed] Admitting she was wrong Moon Girl brought him back as she, Ben Grimm, and Johnny Storm reformed the Fantastic Four and even gave Devil his own uniform.

[volume & issue needed] During the Monsters Unleashed storyline, Devil Dinosaur was with Moon Girl when she was studying the Leviathon attacks.

[50] Moon Girl, Devil Dinosaur and other heroes later encounter other monsters until the Leviathon Queen is defeated by Kei Kawade and his new creations.

While trying to break Devil out of his cage, Moon Girl meets Leer, the Inhuman Karnak mentioned, who knocks her unconscious when the Helicarrier crash lands.

[61][62] An alternate universe variant of Devil Dinosaur, amalgamated with Tippy-Toe and Monkey Joe, appears in Infinity Wars.
