-Has two of the strongest devil fruits in the verse
-In 2 years he made more progress than all other 3 yonko combined
-Scarred Shanks, second most skilled swordsman, and inspired his jolly roger
Meme and Kaido served as filler villains for the main characters to get powerups, that's all I need to know lol
Shanks did nothing besides get scarred by Blackbeard, his only testament is being equal to Mihawk at some point but now that he lost his arm he can no longer compete. The 2 stars of this pirate era are Blackbeard and the main character.
