I don't think the vampires can win this thread, ever. But there's also vampires that Hancock will never be able to kill because of their "special" gifts.
Meaning, no one can actually win this thread.
But, FA wants to say that those other vampires' powers don't count until the movie comes out. So I'll revive about a dozen threads when Breaking Dawn comes out.
Well, thats assuming he knows whats up with the Vampires. OP doesn't say they are aware of each others powers.
So theres no reason for Hancock to blitz her from the get-go (even if he did her mind is fast enough to react IMO, although I will entertain the idea that she is caught off-guard by his speed). There are many targets on the battlefield, thats ALL Vampires and Werewolves from Twilight. Wolves will probably engage first.
Arguing from the other side, the Vampires/Werewolves will think they can take him down no problemo, some will get torn apart when they try and tango with him, but Jane will use her powers on him, and he won't know to avoid her.
And as Rob said, Hancock will fight like the way he fought Mary.
Hancock CIS off/full potential AND awareness of enemy abilities? He would take it easily. In this battle, I don't think so.
Bella's head would turn to goo in the process because his buttcheeks are too hard.
Also, if he tried to shove a vampire Bella's head up Edward's ass, Edward's ass would crack off his crack...his two little rump roasts would break right off.
The movies are going to have a hard time showing the times when Bella kisses edward and she describes it in the books a "kissing cold stone". How are they supposed to show his flesh as completely unyielding to a meatbag while trying to get 13-year olds to sigh with their moms?
Everything about him was hard as a rock, to Bella, before the
change to a vampire. It was only after the change that Bella could feel the "softness" of the "flexible" stone.
Hancock has the actual visual effect of breaking the sound barrier, he does not need to build up speed, he goes from zero to max pretty much instantly when he needs to IIRC.
And yes, escape velocity does apply to him. So at the very least he is Mach 34...but in truth he's far faster than that.
After he carved the hearts logo on the moon (before anyone noticed and thus it would require immense mental processing speeds/reaction time) he came back to Earth in very same night. The way he made it sound, it was all done in mere minutes too--the carving and the travel back.
At Mach 34, it would take him roughly 9 hours to get back, and it did not take him anywhere close to that.
