HONG KONG (AP) — Hong Kong pro-democracy protesters donned cartoon character masks and formed human chains across the semiautonomous Chinese city on Friday night, in defiance of a government ban on face coverings.

Gathering along the city's subway lines, many protest supporters masqueraded as Winnie the Pooh or Guy Fawkes.

Chinese internet users have joked that Chinese President Xi Jinping resembles the talking bear, leading the country's censors to scrub online references to the character. Fawkes masks have come to represent anti-government protests around the world.

The protesters were taking a lighthearted approach to oppose the government's decision this month to invoke colonial-era emergency regulations banning face masks at rallies as it struggles to contain the chaotic protest movement.

Hong Kong's leader has said the ban on masks, which have become a hallmark of the protests, is aimed at deterring radical behavior.

But the protesters say they wear them out of fear of retribution and concern that their identities will be shared with China's massive state security apparatus.

Some protesters out Friday assumed the identity of Xi or Hong Kong's deeply unpopular Beijing-backed leader, Chief Executive Carrie Lam. Others wore masks depicting Pepe the Frog, a character that has become a symbol for the Hong Kong protesters unaware of its association with far-right extremists in the U.S.

At least one protester parodied NBA basketball star LeBron James. James has been criticized for caving to China's communist leaders after he suggested free speech can have consequences, following a now-deleted tweet by Houston Rockets general manager Daryl Morey in support of the protests that angered Beijing.

The protesters' aim was to form human chains extending 40 kilometers (25 miles) across Hong Kong by tracing the city's subway system, mimicking a similar event in August. It's unclear if they achieved that. There were gaps in a part of the chain in one downtown location.
