Ok, now it's no secret that I am quite the Surfer fan. However, DP has this one in the bag. Surfer has NO chance against her barring PIS. Killing Jean with the Phoenix energy signature, is a lot harder than killing her without it. Surfer would be killable by Wolverine or the Shiar if he were in his vulnerable state(without the Silver), but with it it's a whole different thing. Surfers a badass, but the Phoenix Force has been shown to take down Galactus, and Surfers power is only a fraction of Big G's. In a fight between the two, DP would have forcefields and such, so it's not like a single blast from Surfer's going to have that much of an effect.
