Dyon Sai/Abilities and Powers

Dual Daggers/Spear Style
Dyon possesses two daggers that can combine to form a dual edged spear, and it is assumed that he's incredibly capable of using this style. Not much else is known.

Haki
It's been said that all Vice Admirals and above have Haki, so it's safe to assume that Dyon possesses some form on Haki. Though what he knows and how he uses it have yet to be revealed.
