Unlike the Straw Hat crew fighting for justice or the Red Hair Pirates known for their chivalry, Marshall D. Teach’s Blackbeard Pirates embody ruthlessness, pragmatism, and cunning. These so-called villainous traits make them one of the most formidable forces on the quest for the One Piece treasure.
1. A Powerful and Seasoned Crew

Every member of the Blackbeard crew was already a heavyweight before joining. There’s Laffitte, a former sheriff with a dark past, Kuzan (Aokiji), the ex-Admiral with the power to freeze entire oceans, and Shiryu, the infamous former warden of Impel Down.
Beyond that, the core of the crew consists of the most dangerous death row inmates from Impel Down’s level 6. This means the Blackbeard Pirates are not only physically strong but also highly experienced, fearless, and ready to face the harshest situations without hesitation.
2. A Crew Full of Devil Fruit Users

While other pirate crews balance Devil Fruit users with Haki users, Blackbeard’s strategy is to stack special powers among nearly all key members.
All ten captains under Teach wield deadly abilities. This gives them a huge advantage in both one-on-one fights and large-scale battles, making it difficult for opponents to predict their moves.
3. Smart Selection of Devil Fruits

Blackbeard doesn’t collect Devil Fruits randomly. He understands the curse of the sea that comes with eating a Devil Fruit and has carefully planned backup strategies.
Van Augur’s Wapu Wapu no Mi (Teleportation) allows instant movement of allies out of danger or quick approach to targets.
Stronger, Doc Q’s horse, has the Uma Uma no Mi (Model: Pegasus), enabling the crew to move through the air. This provides a perfect escape option if their ship sinks or they’re trapped at sea.
4. Strategic Vision and Reckless Boldness

Marshall D. Teach has an exceptional political eye and world awareness. He knows exactly when to seize opportunities, like intercepting the Supernovas after the Wano battle to steal a Road Poneglyph copy with minimal effort.
The Blackbeard crew is also daring. Sending only Kuzan and Van Augur to infiltrate the Whole Cake Island and kidnap Pudding right under the noses of powerful Sweet Commanders like Katakuri and Cracker shows that for Teach, higher risks mean greater rewards.
5. Flexible Organization and Multi-Target Operations

Their structure allows splitting into smaller teams to handle different missions simultaneously without losing effectiveness. While one group led by Teach hunts Trafalgar Law, another can defend Hachinosu Island and fend off legendary Monkey D. Garp’s assault. This flexibility maximizes their strength across multiple fronts.
6. Maximum Efficiency by Removing Emotional Barriers

The biggest difference between Blackbeard’s crew and more heroic pirate crews is the absence of sentimental bonds. There is no idealistic friendship or blind loyalty here, only mutually beneficial relationships.
This coldness allows them to make ruthless decisions: sacrificing comrades, betraying allies, or retreating immediately if it’s not advantageous. Their brutal pragmatism turns the Blackbeard Pirates into an incredibly efficient treasure-hunting machine that’s hard to defeat through psychological tactics.
