Classification: Human, King (Green King), Green clansman
Threat level: Tiger+
Physical strength: Large building+ (Considerably stronger than all the other kings besides the Gold King)
Destructive capacity: At least city block+, likely higher (Stronger than any of the current kings, the Red King's final attack to Adolf K. Weismann caused a large crater. Stated to be capable of possibly single handedly defeating the Silver, Red and Blue kings all at the same time.). Unknown if his Sword of Damocles would cause the same effect as the other Kings considering Nagare has a special condition in which he is only being kept alive by that power in the first place.
Durability: At least city block+, likely higher (effortlessly blocked attacks from the new Red King, Anna Kushina)
Speed: Likely hypersonic (A speedster even in comparison to the Kings, blitzed the Red clansmen, including new Red King Anna Kushina and her #2, #3 and #4 all in an instant)
Intelligence: Very high.
Stamina: High. Above an average human, but far inferior to the other Kings as he can only use his powers for short periods before it fades.
