Alias/aka: Marshall D. Teach, "Blackbeard", The fourth Yonkou (nickname and eventually title earned after the Marineford war events)
Classification: Human pirate, Devil fruit user (Logia type, darkness man), (former) Shichibukai, Yonkou (pirate emperor)
Threat level: Dragon+
Physical strength: At least city+ (Ace noted how Blackbeard's blow to his neck felt strong enough to rip his neck off), at least island+ level striking with Gura Gura no mi amp
Destructive capacity: At least island+
Durability: At least island+ (survived a slash from enraged "WhiteBeard"s bisento and an attack from an enraged Sengoku)
Speed: At least massively hypersonic+ (via scaling, should have observation haki which grants a sort of extra sense similar to spidey sense which lets him sense things slightly ahead of time.)
Intelligence: Genius. His misleading appearance and usual attitude hide the true cunning of Blackbeard whom is a genius at planning. He succesfully layed low for many years in Whitebeard's crew to obtain the specific devil fruit he needed, manipulated the World Goverment and Whitebeard pirates to play into his plans and claimed the opportunity of the chaos caused in Impel Down by Luffy to gather members from the prisoners there to form one of the most fearsome pirate crews in the world. Another feat worth noting is that with his cunning tenacity and ferocity he managed to wound Shanks, one of the four Yonkou and according to Shanks own acceptance it was not something which happened out of mere carelessness.
Stamina: Very high. Although he has a tendency of being very expressive about his pain to the point it some times can be overreacting, he in reality is extremely resilent. He has taken attacks from Luffy head on, and even been pierced by Ace and slashed Whitebeard yet still continued to be in fighting conditions.
Standard equipment: Multiple guns in his belt (although he apparently doesnt actually use them much in combat)
