Wai-San Chang, better known as Mr. Chang, runs a Triad operation out of Thailand. He's best known for his exceptional skill with dual pistols—a Beretta 76 and an AMT Hardballer—wielding them in a gun fu style that puts even Revy to shame. In fact, Revy has openly admitted she's "not on his level yet," which is pretty remarkable coming from someone who rarely acknowledges weakness. It's heavily implied Chang taught her the technique in the first place, and his mastery of gunplay is likely why he's the only man Revy actually calls "Sir."
Fans often note that Chang's character draws inspiration from Chow Yun Fat's iconic roles in John Woo films—particularly Mark Gor from A Better Tomorrow and John Lee from Replacement Killers. The parallels are obvious: Triad connections, dual-wielding pistols, and similar fashion sense.
What sets Chang apart from typical crime bosses in the area is his pragmatic approach to business. Rather than relying on ruthless dominance, he advocates for cooperation and joint ventures, making him a more calculating and strategic operator than many of his competitors.
