I loved in the astral fight with Charles when Charles is beating on him and says "you're I my house now" and then Apoc catches his fist, his eyes go white, and he announces "you'll need a bigger house" before growing huge. It was another of many moments fromApoc I love in the movie. Him destroying a city with no mercy at all for the occupants was also another.
Such an under rated villain for me, and I love how he was taking on Beast, a charged Magneto, Cyclops and Charles all at the same time, and they still couldn't beat him. It took Pheonix totally unleashing to begin his downfall, and even then Storm had to get involved to finally kill him off..
