Vergo was a powerful man who was confident that he was above an opponent like Trafalgar Law, who is strong enough to become a Shichibukai. This was backed up by easily defeating Law twice, although he had Law's heart to weaken and incapacitate him before their confrontations. In either case, Doflamingo had enough confidence in Vergo to entrust him to kill Law in the most brutal method possible.[14] He was also strong enough to completely overwhelm the entire Unit 01 of G-5, including Tashigi, but (minus Smoker at the time) despite their superior numbers.[6] He defeated Vice-Admiral Smoker with moderate difficulty.
He was shown to have a high level of physical endurance, durability, and resilience as he was able to shake off a direct kick to the head from Sanji, who had strengthened the blow with Diable Jambe (although the attack did cause him to spit out blood), which sent him through a metal wall, followed by an additional barrage with few wounds.[19] He was able to take even Law's Counter Shock, which was strong enough to take out one of the Yeti Cool Brothers with a single blow, with little damage.
He possessed incredible physical strength, as with one kick he was able to fracture a bone in Sanji's leg. Vergo was also remarkably fast, as shown when Law used his Room ability to retrieve his heart and Vergo immediately appeared in front of him and sent him flying with a kick.
Being a vice admiral and head of G-5, he had command over lower ranking subordinates, as well as control over the entire base.[4] He was also skillful enough to deceive the entire Marine force, including the observant Smoker, in hiding his true affiliations, as well as deceiving citizens with pretexts by falsifying the crimes into "accidents at sea".[2]
