In Regards to Slade's SP:

MASTER TACTICIAN: Deathstroke can use Outwit. Modify Deathstroke�s attack value by +1 for each adjacent opposing character. When Deathstroke makes a close combat attack, he can compare the attack roll to the defense value of any number of adjacent opposing characters (minimum 1); the damage dealt by the attack can be divided in any way among the successfully hit targets provided that all damage dealt is divided among them.


Who does the dividing ?
Is it the player dealing the damage (i.e. Deathstroke This makes more sense)
or
The player taking the damage ?

The active player (i.e., the one attacking) always gets to make decisions like this.

What NBPerp said. Its a similar situation as a figure making a ranged combat attack against multiple targets and hitting more than 1 target. The active player divides the damage any way he/she sees fit.

This guy will be very deadly -- he has the potential to do a flurry blades attack with a high AV (9+x) and then divvy it up yikes !

I'm not contradicting Norm here. I'm just adding that in ALL situations, the active player is the player whose turn it currently is.

I see no way for this to ever be different that the attacking player for this figure, but you never know what might come at some point down the road.
