The Beast recently assisted Agent Brand in shooting a huge laser canon through a dimension portal to a bunch of bad guys that were about to invade. It was theorized to kill at least everyone within 10 miles (including a crazy Forge, who seems like he's "getting better" from that). Beast also nuked a bunch of bad guys (Shadow Council) in a recent Secret Avengers issue. Both situations were written by the same guy.
If memory serves, Hank McCoy (sporting all-white fur, by that point) was stopping at nothing, including attempted murder, to get control of the Phoenix Force.
