Well, I guess I'll be the first to characterize my scrapper as domesticated. However, I think there are a few addenda to be made to the OP.
"I was fine." This utterance usually follows any situation where, getting bored with the occasional breaks other heroes like to take for some reason, the scrapper charges ahead and begins liquefying the +2 Devouring Earth that the mission is packed with. Seeing the scrapper hit orange in a matter of seconds and eat all the inspirations accumulated in an evening's work, the rest of the team decides to "rescue" him, despite their unpreparedness. Rather than the gratitude any reasonable AT would profess, they are met with an eye roll and an assurance that their little charge was very cute, if not particularly needed. NOTE: This is required even when the scrapper knows darn well he had only seconds to live.
Scrapperlock encompasses more than the previously mentioned conditions. Once it has reached its apex, the scrapper is helpless to do more than tab away from a fallen enemy, move toward the new object of his ire, and mash attacks until that enemy falls as well. Teammates, toggles, Enhancement tray, food, and symbolic conceptualization all fall by the wayside as the scrapper approaches the ideal of "Just run toward the nearest living thing and kill it."
