The new fan-favorite theory centers on Figarland Garling, Supreme Commander of the God Knights. Multiple factors make him a strong candidate:
He is old enough to have fought Whitebeard during his prime.
His strength is immense, making a Yonko-level confrontation plausible.
He was active across the seas after the God Valley incident.
As a top defender of the World Government, he had a motive to confront Whitebeard.
Garling’s character aligns perfectly with One Piece lore, positioning him as the most logical candidate behind the scar.

Some fans insist that only Shamrock’s resemblance to Shanks explains Whitebeard’s comment about the “face that scarred me.”
However, this line could also mean: “Your red hair and aura remind me of the man who scarred me,” not necessarily a literal twin.
While Shamrock eventually becomes a full God Knight, achieving mastery over Haki and swordsmanship, there’s no evidence he had such power early enough to wound Whitebeard before Oden or Roger’s era ended.

The debate continues, but evidence leans more toward Garling being the true culprit behind Whitebeard’s scar.
While the Shamrock theory is intriguing and fun for fans, Chapter 1167 adds new context and brings the fandom closer to solving this long-standing mystery.
One Piece continues to surprise, weaving intricate backstories and unresolved questions that captivate readers chapter after chapter.
