Toronto is ashes. Kim, Stills, Knives, Young Neil, Wallace...Ramona. All dead. Only one man is left to fight the mutated ravaging hordes that have over-run Canada. In the darkest of winters, Scott Pilgrim fights EVERYTHING.
Honestly, given that in one of the books, a hole was punched in the moon as an expression of love, the end of the world for Scott Pilgrim would probably be a 200-page video game metaphor for contemplating suicide on his sofa.
So, yeah. I'm sad it's not a real thing too. But I have a weird sense of humor.
