- Massively hypersonic speed(could outrun Luffy, fast enough to take Doflamingo/his clone without it being able to react)
- Observation master
- Excellent swords skills
- Tremendous strength(sank battleships, eradicating entire pirate crews without receiving as much as a scratch, stopping his high-speed rotation, breaking his neck, and tossing him out of the building)
- Superhuman stamina(even after 6days without food, could still eradicate his opponents with ease)
He is such a threat that Doflamingo was forced to resort to a creative diversion to avoid being killed, using the diversion in itself to counter-attack with an attack powerful enough to cut multiple buildings around without contact when he left his guard down
Currently facing a top executive and dealing comparable damages
And this is with one leg. I'd say he is top executive level. Though with 2 available legs, he was probably Zoro level or maybe even above
