Bomb-Master Cannon

Cannon is a bombseller from The Wind Waker that lives on Windfall Island. When Link first meets him, he acts rude and disrespectful towards the young hero, saying he only sells bombs to those he approves, and he doesn't approve of Link. He sells bombs at ridiculous prices, which is the reason why Tetra and the pirates tied him up, gagged him, stole the bombs and left him alone in his shop. The reason he sells bombs at such high prices is because he is the last person in the world who still works in the bomb industry, allowing him to establish a monopoly on the business. However, after having the experience of being tied up by the pirates and having his bombs stolen, he becomes a much nicer, respectful person, stating that the policy in the Bomb Shop is kindness. Furthermore, he lowers the prices of bombs, this time only ranging from 10 to 30 Rupees.

Trivia

 * Bomb-Master Cannon's attitude change is similar to that of Chudley's from Twilight Princess: they're both rude and snooty when they charge high prices for their items, but become nice and friendly once they reduce their prices.
