Guy Fawkes was an anarchist who tried to blow up parliament. November 5th is "Guy Fawkes Night" where people in the UK light bonfires or fireworks. Fawkes in the game/book/movie is a Phoenix... that literally bursts into fire.Is there a joke with his name? Like, sure, jokes can be made with his name in context of this game, but Fawkes is his actual name, and I don't see any joke with it in context of the actual series.
Feeding Fawkes does do something. It makes me feel better. He's a good bird.
So, there is a joke here, but it was made by J.K. Rowling.
