He used to be a regular dog with small beady eyes and a tongue sticking out, similar to Chouchou, but smaller in size and without a frown.
After Wapol altered him with his Baku Baku no Mi abilities, he now has a box for a head and lenses for eyes.
Hakowan is somewhat disrespectful of others, since he urinated on Wapol when he first met him. Despite this, he is loyal to the former king, as he stood by his side through the entire cover story and beyond.
Sky Island Saga
Wapol's Omnivorous Hurrah
Following his defeat by Luffy, Wapol was forced into complete poverty, living in an unnamed town's garbage dump. Here, he was found by a stray dog that followed—and urinated—on him everywhere he went.
Eventually, Wapol began using his Baku Baku powers to amuse himself by merging random garbage into toys. The dog became swept up among his building materials, having its head merged with a box and two binocular-like lenses. This process apparently did no physical harm to him, and he continued to stay by Wapol's side, serving as a sort of mascot for Wapol's burgeoning toy business.
Wapol, surprisingly, kept the dog through his entire business career, long after he had (re)gained more wealth and status than even Drum's throne had offered him.

Translation and Dub Issues
His name is a portmanteau of the Japanese term for box (箱 Hako?) and onomatopoeia for a dog's bark (ワン wan?). It is translated as Boxer in the English edition of the 7th popularity poll, possibly as a reference to the dog breed.
- Following the timeskip and the establishment of the Black Drum Kingdom, Hakowan appears to have become bipedal, and donned a superhero-esque costume. It is unknown whether this is the actual Hakowan, or (as the anime implies) a toy based off his likeness.
