WARNING: The following contains spoilers for Captain America/Iron Man #2, now on sale
Spider-Man has one of the most iconic rogues galleries in the superhero medium, with many of his foes utilizing dangerous technology to keep up with the Web-Swinger. Despite their typical (almost goofy) animal-theming, they've proven incredibly dangerous over the years.
Captain America/Iron Man #2 (by Derek Landy, Angel Unzueta, Rachelle Rosenberg, and VC's Joe Caramagna) sees Veronica Eden steal the technology of multiple Spider-Man villains. Even without experience using them, she quickly proves to be a deadly threat -- proving how dangerous the Sinister Six weaponry really is.
At the heart of Captain America/Iron Man has been Veronica Eden. A former HYDRA agent who now on the run, she's been trying to stay a step ahead of Captain America, Iron Man, and other heroes chasing her. Along the way, she forces her new ally Fifty-One to stop at an armory containing various superhero and supervillain equipment. There, she effectively ransacks the Sinister Six section and suits up with a hodgepodge of gear. By the time the heroes arrive, Eden's donned a copy of Doctor Octopus' tentacles, grabbed a Scorpion tail, and found a Goblin Glider to fly around on. Quickly abandoned by Fifty-One, Veronic finds herself fighting the two Avengers and the superhero team known as the Paladins at the same time.
Despite her relative lack of experience in the field with all of this equipment, Eden actually does fairly well for herself. She gains an edge on the two Avengers before the interface on the tentacles hinders her long enough for the Paladins to arrive. Eden even holds her own against seven enemies, including two of Earth's mightiest heroes. Luckily for the heroes though, their numbers and her faulty tech leaves her open to be knocked out by Captain America. But it's worth noting just how dangerous Eden really was, even with faulty versions of the Sinister Six technology. Utilizing just three of the devices used by Spider-Man rogues, Eden was openly bragging about winning their fight. She was also not a particularly well-trained fighter, instead serving as a tactician and spy. And yet, she held her own against Captain America.
If the technology had been properly working -- and the Eden had been appropriately trained -- then using all that tech once would have been seriously dangerous. Even how it was, she landed good hits on most of her enemies, even tagging Iron Man with a few solid blows. It goes to show how dangerous the technology of Spider-Man's enemies really is in the wrong hands. There have been plenty of people who have stolen these kinds of weapons and become threats in their own right. Hobgoblin, Lady Octopus, and the various alternate Vultures have all been dangerous with just one stolen weapon. None of them originally designed their gear, utilizing the creations of others to cause chaos. But Eden's ambition hints at how dangerous someone with the right skills could really become if they combined the technology.
While it could be dangerous, it'd be a major boon for someone with ambition and a lack of restraint. If someone like Taskmaster was to get his hands on all that technology, he would likely be far better prepared -- and far more dangerous. Just using his traditional weaponry, Taskmaster had held his own against entire teams of heroes. With that extra edge of the Spider-Rogues tech, someone like Taskmaster could become a genuine Avengers-killer. Even someone like Mysterio has been shown using his technology so well that entire teams turned against one another, like in the Old Man Logan reality. It's a good reminder of just how dangerous Spider-Man's foes really are, that even someone inexperienced with these tools could become a serious threat to long-established heroes like Iron Man and Captain America.
