It's not just any bowler hat, though! It's a distinctive symbol of his villainy, and serves a few key purposes:
* It's a visual cue: The hat makes him stand out from the other characters and helps to establish him as a bad guy right away.
* It's a prop: He often uses the hat to cover his face or to hide his true intentions.
* It's a representation of his past: The bowler hat was part of his original identity as an inventor before he became bitter and vengeful.
So, the bowler hat isn't just a fashion choice, but a crucial part of Bowler Hat Guy's character!
