So who dies in the pages of AVX? It's none other than Professor X himself, Charles Xavier...
Yeah it happens somewhere after this page... What happens is Cyclops goes mad with power and then the combined forces of the X-Men together with the Avengers tries to take him down. Sadly the effort is wasted as Cyclops gets the Phoenix force power from Emma Frost and becomes the main host of the Phoenix force.
This is when he kills Chuck. Wolverine tries to attack Cyke once more but is burned badly. Cyclops then reveals that he has become the new host for the Dark Phoenix. This paves the way for the showdown for AVX # 12.
Another repercussion for this is Legion (Gabriel Haller) embracing his inner hero and living up to his father's dreams and ideals in the relaunched X-Men Legacy.
Whatever happens I'm really excited for what's going to happen later.
UPDATE: Oh and I completely forgot the fact that Hulk (Banner Hulk) has also been recruited by Cap in the first two pages of issue 11. Then Hulk beats Emma Frost but is later beaten by Cyclops. Much props to Coipel for drawing such an amazing rendition of Hulk.
