3. "Ultron, We Would Have Words With Thee"
Voted the "Best Moment of 1999" by Wizard Magazine, this scene occurred in Avengers Volume 3 #22. Ultron takes things too far, even for him, by brutally murdering the entire population of Slorenia and capturing numerous Avengers members including Vision, Hank Pym, Wasp, Scarlet Witch and Wonder Man, as well as the Grim Reaper. He then sets an army of robotic doppelgangers loose on remaining Avengers heroes including Thor, Captain America, Iron Man, Firestar and Black Panther. During the attack, a wall explodes, revealing a disheveled, bloodied and extremely ticked off Avengers conglomerate. Thor speaks on behalf of everyone present when he says "Ultron... We would have words with thee." Awesome - and a moment that could be recreated in the Avengers sequel which is, of course, subtitled "Age of Ultron".
