Doctor Doom is considered one of the greatest comic book villains ever written, but DC Comics also had their own version of Doctor Doom... who actually turned out to be almost the exact opposite.
Victor Von Doom was created by Stan Lee and Jack Kirby in 1962, and first came into conflict with the Fantastic Four in issue #5 of their ongoing series. Doom is the ruler of Latveria, who wants to conquer the rest of the world, and would come into conflict with the Fantastic Four, and other Marvel heroes, many times over the years. Doom has a longstanding rivalry with the Fantastic Four's leader Reed Richards, A.K.A. Mr. Fantastic, and would do anything to prove his superiority to the one man who, time and again, defeated him. Doom is a master of all trades, including technology and magic, which makes him a threat to any of Marvel's other great heroes, such as Iron Man or Black Panther. Though Doom has previously dabbled in heroism, there's no denying that the not-so-good Doctor is as evil as they come. However, Victor isn't the only Doctor to bear the name Doom, as DC themselves had a "Doctor Doom," one that predates Stan and Jack's own creation.
DC's Doctor Doom was introduced in 1950's Detective Comics #158 in a story titled "The 1001 Trophies of Batman," written by Edmond Hamilton and drawn by Bob Kane. This Doctor Doom (who has no alter-ego or other name) is not a scientific genius, but rather a smuggler of priceless artifacts and jewelry who has eluded Batman and Robin. The story begins with Batman and Robin reflecting on some of their most interesting trophies in their trophy room (such as the famous giant penny and dinosaur). Their trip down memory lane is interrupted, as Commissioner Gordon calls Batman to inform him that Gotham P.D. has Doctor Doom cornered at the docks. When Batman and Robin arrive, Doom claims that he has done nothing wrong, and that all his goods are legitimate. After examining one, Batman deduces that it is not only a fake, but rather a duplicate that holds priceless jewels that Doom tried to smuggle into Gotham. Doom, preferring death to defeat, attempts suicide by jumping off the side of the docks. After awhile, Gordon and Batman decide that Doom surely must be dead, as he had yet to emerge from the water. As thanks for defeating Doom, Gordon offers Batman a sarcophagus that Doom smuggled into Gotham as another trophy. However, Doom's story is far from over.
While Batman and Robin are talking with Gordon, Dr. Doom reemerges from the water (having used his cigarette holder to breathe underwater unnoticed) and discretely hides inside the sarcophagus. Without either of our heroes realizing it, Doom ends up taking a ride with Batman and Robin back to the Batcave, being able to breathe through the sarcophagus through the cracks around the cover. Once Batman and Robin place the sarcophagus in their trophy room, Doom realizes that he has arrived in Batman and Robin's headquarters, but is unable to leave the trophy room. Doom decides to eliminate the dynamic duo, and begins to transform their trophies from inert objects into deadly death traps. Batman receives an alert from Wayne Manor that someone has invaded the Trophy Room (but hasn't caused chaos throughout the rest of the cave). When both heroes don their costumes and head to the cave, they enter the trophy room to find no trace of anyone there. However, that's when Doctor Doom's "master plan" comes to fruition.
One by one, the trophies start attacking Batman and Robin, with the giant penny almost crushing Robin, and giant dice almost crushing Batman. Both Batman and Robin immediately suspect foul play, as all of their trophies were rendered harmless in the Cave. Batman then suspects that Doctor Doom has invaded the cave, as this act of sabotage occurred shortly after they brought the sarcophagus into the Cave, and though no-one is found in the sarcophagus, it was still wet from Doom's time in it. Doom then reactivates the giant dinosaur, and once Batman and Robin discover the villain and disable the dinosaur, the villain makes his way back to the sarcophagus. Doom then grabs a grenade (one of Batman's trophies) and throws it at Batman and Robin, hiding in the sarcophagus to protect himself from the blast. While Batman uses a sturdy model house (another trophy from the cave) to protect himself and Robin, they find that the sarcophagus has been sealed, with Doom inside of it. Because the sarcophagus was sealed so tightly, there were no airholes that Doom could breathe through, thus suffocating the villain to death, and though Batman and Robin were able to free the body, it made the sarcophagus one of their more disturbing "trophies."
This incarnation of Doctor Doom is far from worthy of the name itself, as he makes several blunders throughout this caper. Doom makes little effort to hide his fake artifact from Batman, the one that held evidence of his smuggling crime. Rather than escaping from Batman and Gordon at the docks, Doom opts to hide in his own sarcophagus, an item that would surely have ended up in police custody, if not Batman's. While turning Batman's trophies against him was an interesting idea, throwing a grenade at him while ducking for cover was pretty bland by comparison, and ultimately led to his downfall. While many characters between Marvel and DC are similar to each other in some ways (such as the X-Men and Doom Patrol, or the Fantastic Four and the Challengers of the Unknown) they have their own unique characteristics and powers that make each character great in their own right. In this case however, this Doctor Doom is objectively worse than Marvel's Doctor Doom, and shares very little in common with the powerful dictator.
While DC's Doctor Doom is nothing more than a footnote in Batman history, Marvel's Doctor Doom is still one of the all time greats, proving that there's more to being a supervillain than having a cool name.
