Most memorable Aspects?

[Mr. Death]

Ninja School Drop Out: my character likes to disappear, creep up on someone and whisper, "Ninja," in his or her ear.

I'm now imagining this sung to the tune of "Beauty School Dropout" from Grease.

I have to say, there was the "Holy Pickup Truck of St. Green", that I'm quite fond of. It was one of the first aspects created in my game, when the holy guy blessed a truck to ram the giant stone jaguar to take it down. It failed spectacularly, but it was pretty cool.

Then, there's the classic: "Knight to C4" for a knight of the cross demolitions expert.

I remember that! If memory serves I was thrown clean off the back and had to take some stress from the landing

"Most" memorable depends, to me, on the context of the character and the game going at the time.

In one game I had a player construct a former KGB agent who had gone about as around-the-bend PTSD as he could w/o a padded cell. He had 3 very juicy aspects,
1. Unstable KGB Mercenary
2. Neurotic Badass
3. Pain Is My Mentor

He was always in trouble...

In another I had someone trying to emulate something Kincaid-ish. "In Cold Blood" was used a lot with that one, especially when paired with his "Right Place, Wrong Time" aspect. Could hardly as for more grist.
