Marvel Comics Spider-Man Neogenic Nightmare Chapter 4: The Mutant Agenda

S2, E4: Spider-Man's progressing neogenic mutation is making him ill and he seeks the aid of Professor Charles Xavier. In doing so he meets the X-Men but is disappointed to learn that Xavier does not 'cure' mutancy, only helps those born that way to accept and control their abilities. Later Beast tells Spider-Man to go to Dr. Herbert Landon who is working on a cure for mutants. When Spider-Man leaves, Landon's men kidnap Beast. While Peter is watching Landon's demonstration Hobgoblin attacks the facility and brings down the ceiling because Landon tried to kill Hobgoblin earlier.
