[@malmshodes] Thats a sweet sounding fruit. I can imagine it would suit him a lot. He can sick someone to assault his enemy and than from the shadows to negate a ability of skill rendering the person more less helpless in front of the assault the employer got. 

Hm.. how about he can negate as long as he watches what he is negating. So watching a devil fruit user he can negate the devil fruit ability as long as he sees them? *wonders if going with this idea of having to see, if the video snails would be a weak link as he could sees people over a monitor?*
