Sweet screenshot!
I am a chronic re-roller, so I've never seen a DB Scrappers higher attacks, but I noticed that you not only sliced them with two energy swords, but you managed to insert miniature exploding stars in all three of their chests for an extra little bonus! Congrats!
The attack is Sweeping Strike, the DB attack that opens up at level 26. The visuals are all regular in-game effects. Those energy blades are the Vanguard "costume" pieces for the Dual Blades, recolored to the general theme of the costume, and the little sparkly explosions actually appear whenever you hit with a bladed weapon in most attacks in most powersets. I just happened to snag a screenshot of it just as they went off.

So I was tooling around in my screenshots directory and found this. I considered it quite the action shot, and when I looked at it closely, it struck me that it really doesn't look like these guys are going to jail unless someone there is going to stitch them back together. A quick trip to an on-line (de)motivational poster maker, and voilá ...
