I once browsed a 3 million word fanfiction (see: skipped to the end) where it was all about Harry's kids, and Albus Severus was the main character. The final climatic chapter had him, in true people who are named Albus fashion, single handedly destroying 100 dark wizards (including a new dark lord) without them even breaking his shield. It was the most hilariously epic stomp I've ever seen, and it was only so because I hadn't read more than a couple thousand words of the story before skipping ahead.
