Wapol is such a weirdly memorable character in 'One Piece'—like, he’s this absurd, gluttonous king with a ridiculous Devil Fruit power, but Oda somehow makes him matter beyond just being a joke. He first appears as the tyrannical ruler of Drum Island, where his selfishness literally destroys the country’s medical system, setting up Chopper’s tragic backstory. But what’s wild is how he keeps popping up later, like a bizarre running gag with actual consequences. Post-timeskip, he’s rebranded as 'Wapolmetalia,' selling cheap toys made from his ability to merge objects, which is both hilarious and weirdly fitting for the series’ theme of resilience.
What I love is how Oda uses Wapol to contrast Luffy’s leadership. Luffy’s crew would die for him; Wapol’s subjects rebelled. Even his power, the Baku Baku no Mi, reflects his greed—he eats anything, but it’s never enough. Yet, in typical 'One Piece' fashion, even a loser like him gets a second chance, proving the world’s bigger than just the main crew’s adventures. He’s a small-scale villain who still leaves a dent in the story.
