query: What immoral activities is the Ultimate Marvel version of the Roxxon Corporation responsible for?
answer: The Ultimate Marvel Roxxon Corporation is responsible for various immoral activities and is led by the inept heir Donald Roxxon.  They fired Elijah Stern after he discovered a way to use vibranium as a power source, taking credit for his work.  They also used guinea pigs in experiments to create super-soldiers (Bombshell, Spider-Woman, Cloak and Dagger), and experimented to restore the Venom Symbiote.
