Alright, I'm making this after just finishing a reread of Morrison's entire run of New X-Men. The book is full of all kinds of incredible stuff, but there's one scene that always just nails me. After a ton of stuff happening including the destruction of Genosha, it is revealed that Professor X
Is actually his evil twin Cassandra Nova who wants to destroy all Mutants and is about to get on board a Shii'ar super destroyer. He/she proceeds to drive Beast feral and then have one of the students beat Beast nearly to death, then calmly go on to link up with the Shii'ar and wreck their empire.
Now, as great as the comic alone was at that time, this moment really energized comics for me and just floored me in general. I sat starring at the reveal page for half an hour trying to comprehend just how far reaching the effect of what happened was. It really just amazed me how effective that two page reveal was.
So this thread is mostly just for us to discuss the really heavy moments in comics. What point in any run was effective for you? When did you realize the potential that the comic book medium held as an art form? When did the artist and writer just find the perfect way to draw you into a compelling story?
