The world of One Piece is built on the legacies of legendary pirates and marines like Gol D. Roger, Whitebeard, Kaido, Big Mom, and Garp. But just as fascinating are the children who carry their bloodlines, inherit their wills, or reject their ideologies entirely. These next-generation characters shape the balance of power in the modern era and are vital to understanding One Piece’s present and future.

Here’s a ranked list of the top 10 strongest children of One Piece's older generation, including confirmed and heavily implied descendants of iconic figures like Rocks D. Xebec, Figarland Garling, and the pirate king, Gol D Roger.

Marshall D. Teach (Blackbeard)

Marshall D. Teach aka Blackbeard — Marshall D. Teach, the only known man to use two devil fruits.

Parent: Rocks D. Xebec

Affiliation: Blackbeard Pirates, Yonko

Powers: Yami Yami no Mi (Darkness), Gura Gura no Mi (Quake)

Blackbeard is the most dangerous pirate in the current era. As the only known person in history to wield two Devil Fruits, his power rivals or exceeds any Yonko. His connection to Rocks D. Xebec, one of the most feared pirates ever, positions him as the heir to a legacy of chaos.

Shanks

Parent: Figarland Garling

Affiliation: Red-Haired Pirates, Yonko

Powers: All three advanced Haki types (Observation, Armament, Conqueror’s)

Shanks is not only a Yonko but also a member of the Celestial Dragon Figarland family, giving him ties to both pirate royalty and the World Government. His ability to halt wars with his presence and the mystery surrounding his power make him one of the most influential characters in One Piece.

Monkey D. Dragon

Parent: Monkey D. Garp

Affiliation: Revolutionary Army (Supreme Commander)

Powers: Unknown

Dragon, the father of Luffy and son of Garp, is known as the world’s most wanted man. As the leader of the Revolutionary Army, Dragon poses the greatest threat to the World Government. Though his full abilities remain unseen, his influence is undeniable.

Monkey D. Luffy

Parent: Monkey D. Dragon (Grandparent: Monkey D. Garp)

Affiliation: Straw Hat Pirates (Captain), Yonko

Powers: Gomu Gomu no Mi / Hito Hito no Mi, Model: Nika; All advanced Haki

As the grandson of Garp and son of Dragon, Luffy is a direct product of one of One Piece’s most legendary bloodlines. Now a Yonko himself, Luffy’s awakening of the Sun God Nika’s powers has made him a symbol of liberation and chaos across the seas. His strength, charisma, and inherited will make him one of the most impactful descendants of the older generation.

Prince Loki

Parent: King Harold

Affiliation: Nation of Elbaf

Powers: Possible Unknown Devil Fruit (Giant strength, implied Haki mastery)

Loki, the giant prince of Elbaf, carries the weight of his lineage as the potential future king of the land of warriors. Though his full abilities are still unknown, his status as royalty among giants suggests immense strength and influence. With Elbaf now playing a central role in the Final Saga, Loki’s true power and political importance could reshape the balance of the seas.

Portgas D. Ace

Parent: Gol D. Roger

Affiliation: Whitebeard Pirates (2nd Division Commander)

Powers: Mera Mera no Mi (Flame), Conqueror’s Haki

The son of the Pirate King, Ace inherited the will of D and was destined for greatness. His tragic death during the Marineford War was a pivotal moment in the series and continues to impact the story through characters like Luffy and Sabo.

Yamato

Parent: Kaido

Affiliation: Ally of the Straw Hat Pirates

Powers: Inu Inu no Mi, Model: Okuchi no Makami (Mythical Zoan), Advanced Haki

Yamato is Kaido’s rebellious daughter who idolizes Kozuki Oden. With powerful Haki and a Mythical Zoan Devil Fruit, Yamato helped hold off Kaido during the Onigashima Raid, proving herself as a top-tier warrior.

Charlotte Katakuri

Parent: Big Mom

Affiliation: Big Mom Pirates (Sweet Commander)

Powers: Mochi Mochi no Mi (Special Paramecia), Advanced Observation Haki

Katakuri is Big Mom’s stronger child. His ability to see slightly into the future, combined with his combat prowess and honor, made him the toughest opponent Luffy had faced pre-Wano. He embodies what it means to be a commander of a Yonko crew.

Shamrock

Parent: Figarland Garling

Affiliation: Holy Knights

Powers: Cerberus sword

Shamrock is the commander of the God's Knights and his connection to Garling and by extension the Five Elders, makes him a person of interest. His brief appearance on Elpaf could lead to him becoming a major player in future arcs.

Edward Weevil

Parent: Allegedly Whitebeard

Affiliation: Former Warlord of the Sea

Powers: Superhuman strength (comparable to a young Whitebeard)

Though his origins are in question, Kizaru himself stated Weevil’s strength was on par with Whitebeard in his youth. Weevil is a destructive force and a wildcard in the balance of power.
