X-Men/Avengers: Onslaught Omnibus brings the mutant line and the wider Marvel universe together around a psychic threat born from the darkest edges of heroism itself. Fabian Nicieza, Scott Lobdell, Adam Kubert and Andy Kubert give the event the huge crossover force of the 90s, with Xavier’s dream twisted into something terrifying. The appeal is the scale and the discomfort. Onslaught is frightening because he is not an outside invader in the usual sense; he is born from ideals, trauma and power twisted until the Marvel universe has to answer for them.
