DC Comics sent McKay a cease‑and‑desist letter, claiming Fanman's red, blue and yellow colour scheme, cape, boots and chest emblem closely resemble Superman and could mislead shoppers into thinking the business is licensed or endorsed by the comic‑book publisher.

McKay has hired a lawyer and says he will keep using Fanman while he contests the claim, stating he enjoys dressing up for fun and does not believe anyone thinks his shop is linked to the DC universe.

Intellectual‑property expert Sarah Hook explained that social media and AI tools now let large brands quickly spot potentially infringing uses online, which is why more enforcement letters are being sent to small companies.

Hook advises businesses to search IP Australia's free trademark register before finalising logos, names or branding, so they can avoid costly disputes like the one facing McKay.

Similar trademark battles have hit other Australian small firms, such as a gym in 2013 that was sued by DC Comics over a Superman‑style workout program and swimwear brand Swim Shady, which successfully defended its name against a challenge from rapper Eminem.

The Fanman case shows that early IP research and awareness of AI‑driven brand monitoring are essential for small businesses that want to protect their branding investments and stay out of costly legal fights.
