Blackbeard Is Set To Acquire Kuma's Nikyu Nikyu No Mi

While many speculate that Teach's third Devil Fruit will be a Zoan type, I have reservations about that possibility. Zoan fruits demand mastery, and I don't believe it aligns with the type of Devil Fruit Teach is seeking. Luffy already wields a Zoan fruit, and it seems unlikely that Oda would give Teach a similar power, ensuring Luffy retains some chance of victory.

Teach's primary weakness lies in his lack of mobility, a flaw evident in his battles. Unlike other top-tier individuals like Big Mom, who can enhance her speed with Zeus, Teach lacks such advantages. His vulnerability to attacks was apparent when Law's Kroom easily hit him, a feat he struggled to accomplish against Big Mom even with Kid's assistance. Later in the fight, even Bepo managed to land a hit on him, a situation uncommon among top-tier fighters.

While Teach is undeniably strong, his mobility weakness sets him apart from the likes of the strongest Yonkos, such as Kaido and Shanks, who can swiftly blitz opponents. Teach has yet to showcase such speed. His only one-shot victory against Hancock was due to a cheap shot when she was preoccupied with Koby. Rather than a Zoan fruit, what Teach needs is a Devil Fruit that enhances his speed, and the Nikyu Nikyu no Mi seems to provide precisely that. With this ability, his mobility issues would be resolved, allowing him to teleport in front of opponents and strike with the Yami Yami no Mi or Gura Gura no Mi.

Moreover, the Nikyu Nikyu no Mi addresses another of Teach's vulnerabilities—his sensitivity to pain, intensified by the Yami Yami no Mi. Teach struggled with pain when attacked by pre-skip Luffy in Impel Down. However, he seems to have adapted to the Yami Yami no Mi's pain, as evident in his resilience against Law's shockwave. With the Nikyu Nikyu no Mi, Teach could redirect his amplified pain onto his adversaries, creating a dark parallel to Luffy's rubber-like resilience.

Considering Kuma's impending demise, the Nikyu Nikyu no Mi will need a new wielder. Among the available options, Teach appears to be a strong contender for acquiring this formidable Devil Fruit.

Blackbeard's Third Devil Fruit: More Than Just Mobility?

While the idea of Blackbeard seeking a Zoan Devil Fruit for his third power holds merit, your argument for the Nikyu Nikyu no Mi offers a compelling alternative that addresses more than just mobility issues. Here's a breakdown of your points and some additional thoughts:

Zoan vs. Nikyu Nikyu no Mi:

Zoan mastery argument: You raise a valid point about Zoans requiring training. Blackbeard, known for his pragmatic approach, might favor a more immediate power boost.
Uniqueness and thematic considerations: Luffy's Zoan doesn't necessarily preclude Blackbeard having one, but a different Zoan type could be interesting. Still, the Nikyu Nikyu no Mi's unique abilities offer a strong thematic contrast to Luffy's rubber and fit Blackbeard's manipulative style.

Addressing Blackbeard's Weaknesses:

Mobility: You're right, Blackbeard's lack of speed is a significant disadvantage. The Nikyu Nikyu no Mi's teleportation and repulsion could be a game-changer, allowing him to close the gap and utilize his devastating Gura Gura no Mi and Yami Yami no Mi powers more effectively.
Pain tolerance: The ability to deflect pain onto others aligns perfectly with Blackbeard's cunning and willingness to exploit his opponents' weaknesses. It also creates a fascinating parallel to Luffy's rubbery defense.

Additional Considerations:

Narrative impact: The Nikyu Nikyu no Mi's potential in Blackbeard's hands could raise the stakes significantly, creating a formidable antagonist.
Fruit availability: While Kuma's fate remains unclear, his potential death and the fruit's reappearance would add intrigue to the narrative.
Blackbeard's ambition: Beyond addressing specific weaknesses, Blackbeard's insatiable desire for power suggests he might seek a Devil Fruit that complements his existing ones, not just fixes his limitations.

Conclusion:

Your analysis goes beyond the typical "speed fix" argument and presents a compelling case for the Nikyu Nikyu no Mi. Its thematic fit, potential to address multiple weaknesses, and narrative impact make it a fascinating contender for Blackbeard's third Devil Fruit. Ultimately, only Oda knows what lies ahead, but your theory adds a thought-provoking dimension to the ongoing speculation.
