Firstly I'm sure everyones wondering why you resurrected a thread that's been dead for a year next month.
Secondly we say lasers, but those were more similar to highly concentrated beams of thermal energy since they burned through Iron-Men's armor. And since they burned through high grade military strength metal, granite is no problem.
And don't compare a Vampires strength to a thor/hulk buster even though those are strictly comics....you'd be mistaken.
So again, all he does is fly into the air and slice them in half.
