"Hmm...I don't fully remember the first time I used that attack. I think it might have been that one time...yeah..."

"Pretty sure it was a thug who attacked Pearl. For context, we were battling some grunts who kidnapped Violet, and Pearl tried to get past them to save her. One of the goons was about to throw a knife at her, and you probably know what happened next. I don't FULLY remember if that was the first use of that technique, but as I recall, there was only one casualty in that battle. I should note though that it wasn't a bloody mess, and it never has been. (Un?)fortunately my fists are incapable of causing cranial explosions. But one look through an x-ray should tell you how the name came to be."

"Also, not to be nitpicky, but it's called "Skull Cracker", not "Skull Crusher". Geez, no wonder you had such graphic imagination."
