Devil Dinosaur appears in Hulk and the Agents of S.M.A.S.H., with his vocal effects provided by Steven Blum. In the episode "Smash Land", A-Bomb and Red Hulk (after being knocked off their jet) encounter Devil Dinosaur under Sauron's control ordering to attack. Alerted of She-Hulk and Skaar attacking the drill at the super-volcano, Sauron controls Devil Dinosaur into finishing the attack. Devil Dinosaur ends up swallowing A-Bomb as he then charges towards Hulk. The Hulk and Red Hulk then fight Devil Dinosaur to get A-Bomb out of him. After being freed from Sauron's mind-control, Devil Dinosaur regurgitated A-Bomb as Devil Dinosaur becomes friends with A-Bomb. Devil Dinosaur helps to fight Sauron's forces and destroy the drill.
Devil Dinosaur is brought back with the Agents of S.M.A.S.H. as their 'pet'. In the episode "Red Rover", Devil Dinosaur's antics start to annoy Red Hulk, causing Red Hulk to find someplace to relocate Devil Dinosaur. After trying a petting zoo and a museum, Red Hulk drops off Devil Dinosaur in Latveria (mistaken for Transia). After Red Hulk is captured by Doctor Doom to siphon Red Hulk's gamma energy for Doctor Doom's larger armor, Devil Dinosaur actually rescues Red Hulk as they escape from Latveria. Red Hulk and Devil Dinosaur managed to make their way back to Vista Verde. When Doctor Doom caught up to Red Hulk and Devil Dinosaur, the rest of the Agents of S.M.A.S.H. joined the battle. With Devil Dinosaur's help, the Agents of S.M.A.S.H. are able to fend off Doctor Doom. Afterwards, Red Hulk and Devil Dinosaur have an understanding for each other, at least until Devil Dinosaur ended up burying Red Hulk in the ground again.
In the episode "Homecoming", Devil Dinosaur is locked up in the weapons vault when the Abomination takes over Vista Verde. Devil Dinosaur is later taken by the Leader alongside the weapons present. In the episode "Spidey, I blew up the Dinosaur", Devil Dinosaur goes on a rampage in New York after Leader fed him a gamma bomb that made him bigger. Spider-Man and the Hulks managed to save him before Leader could blow him up. In the episode "Banner Day", A-Bomb mentions Devil Dinosaur's attack on New York, admitting that the Agents of S.M.A.S.H saved the day even though the threat technically was their fault.
In the episode "Days of Future Smash: The Dino Era", a dinosaur-dominated timeline has El Diabio, an intelligent version of Devil Dinosaur who has the power of speech and wears special armor. Alongside Spider-Raptor, El Diablo is among those who fought King Sauron's tyranny. With help from the Agents of S.M.A.S.H., El Diablo and Spider-Raptor were able to free the primitive humans and overthrow King Sauron. El Diablo managed to befriend Moon-Boy. In the past, Hulk encountered a young version of Devil Dinosaur helping defeat Leader's plot that resulted in the dinosaur-dominated timeline. Before pursuing Leader to the next time period, Hulk herded Devil Dinosaur and the other dinosaurs present to the Savage Land to keep them from going extinct. Once all that was done, the dinosaur-dominated timeline shifted to the next timeline.
Devil Dinosaur first appears in the episode "Hulk's Day Out" as a friend of Hulk. In "Westland", he is one of the dinosaurs that was placed in the Westland region of Battleworld. He encounters and attacks Vision, Rocket Raccoon, Groot, and Jane Foster, but returns as an ally in defending the town from Kree robots.
Devil Dinosaur has a cameo appearance in the Guardians of the Galaxy TV series. In the episode "One in a Million You", he appears as one of the creatures in the Collector's zoo.
There are multiple allusions to Devil Dinosaur in the queue of this attraction as Moon Girl is a member of W.E.B., the Worldwide Engineering Brigade. There is a missing poster for Devil Dinosaur on the notice board along with an illustration of him under the welcome message for Lunella. At Peter Parker's desk, there is a figurine depicting Devil Dinosaur and artwork of him on Lunella's locker.
In the comics, it is established that Devil Dinosaur is a Mutant, with his mutation turning his olive-green skin, burning red, and making him more intelligent than other dinosaurs. In some issues he is referred to, species-wise, as a "Devil-Beast" and sometimes a Tyrannosaurus rex.
The appearance of Devil Dinosaur in "Spidey, I blew up the Dinosaur" and "Westland" is based on T. rex illustrations by Mark Hallet and Luis V. Rey.
The animated appearance of Devil Dinosaur & the rest of his kind “the Normal T. rexes” from both Hulk and the Agents of S.M.A.S.H. and Avengers Assemble closely resembles some other animated T. rexes that appeared on animated action shows like Cadillacs & Dinosaurs in 1993 & Kong The Animated Series in 2000.
His roars in Hulk and the Agents of S.M.A.S.H. are the same sound effects used for the T. rexes from the Jurassic Park franchise. Devil Dinosaur on both "Spidey, I blew up the Dinosaur" and "Westland" (including some of his kind in "Days of Future Smash: The Dino Era") had the sound effects of the Large Theropod Dinosaurs from the 2003 Discovery Channel documentary Dinosaur Planet.
In "Coney Island, Baby!" and "OMG Issue 2", Devil Dinosaur was seen swimming. In the 2022 BBC dinosaur documentary Prehistoric Planet, it was revealed that T. rexes could swim with hollow air filled bones & powerful hind limbs.
The appearance of Devil Dinosaur’s ancestor little devil from “Days of Future Smash: The Dino Era” resembles a cross between Agumon and Guilmon from the Digimon franchise.
Devil Dinosaur was given extended mechanical arms in the Second Season of Moon Girl & Devil Dinosaur. Devil Dinosaur was previously seen with mechanical arms from the second season 19th episode of Hulk and the Agents of S.M.A.S.H. as his alternate version El Diablo in “Days of Future Smash: The Dino Era” .
Steve Loter hinted that Devil might learn to speak English at some point.
