Okay, this came up in a game last night -- Harvest the Mighty hits the character with the most cards in play; I was playing Extremist Sky-Scraper and the most cards in play were the three links I'd put on Chokepoint, so she ate the damage. Then it says to take a card from that hero's play area and put it face down in Chokepoint's area. Since none of the links were in Sky-Scraper's play area, the table decided to flip none of them. Is this correct?
Second question, never actually came up, but can you use any part of Huge Extremist's power if there are no environment cards out?
