Dormammu said: I was surprised at how well boosted XFW performed through all 7 rounds as long as he had a black feeder with him that wasn't Doom (since Galactus' strongest color is blue). He might be the single best 4-star this side of Hulkbuster when you just need to take out one enemy. I'm going to start using him in those fights against the Hulk in his PvE event.
