Throughout his career as a professional impersonator he has also worked with multiple organisations and celebrities to create parodies and to stir up conversations of politics and human rights.

In 2021, it was reported that he was raided and arrested at his home by the Hong Kong government, sparking concerns that he was targeted by the ruling Chinese Communist Party.

He had dressed up like Kim Jong Un for April Fool's Day, and upon sharing a picture on Facebook, an Israeli fast-food chain Burger Ranch hired him for a television commercial.

He starred in the bubble tea parody commercial by the Taiwanese global franchise teahouse Chatime which aired on SBS and Pop Asia in Australia and he was also featured in a Schlag den Raab promotion among other celebrity impersonators which was aired on German television channel ProSieben for the new season of the live game show such as Chuck Norris, Lady Gaga, Johnny Depp, Queen Elizabeth and Pope Benedict XVI impersonators.

[37][38][39] In a mini documentary produced by Urban Tales, Howard X shared that he spent at least two hours to get ready for his Kim Jong Un look, constantly studied his mannerism and had to be updated with everything that's happening in North Korea.

[42][43] In December 2017, Howard X starred in the viral official music video of Russian rave band Little Big’s Lolly Bomb.

[45] In the same year, there was also a comical television commercial produced by Film Factory Hong Kong for Wilson Communications featuring Donald Trump, Kim Jong Un and Vladimir Putin impersonators.

[47] In early February 2018, Donald Trump impersonator Dennis Alan and Howard X made headlines on many news channels for their appearances together at the PyeongChang Winter Olympics opening ceremony.

"[63][64] During 2018 FIFA World Cup, Vladimir Putin impersonator Steve and Howard X travelled to Samara, Russia for the Russia-Uruguay match.

[65][66][67][68] In February 2019, Howard X joined Rodrigo Duterte impersonator Cresencio Extreme in attending an hour-long service at St Joseph's Church and at Filipino fast-food restaurant Jollibee while eating fried chicken.

Phil Robertson, the deputy Asia director for Human Rights Watch, said that it was "truly absurd and despicable" that Vietnam was harassing and threatening Howard X.

The government-proposed bill prompted a series of 2019–20 Hong Kong protests as it would allow the extradition of suspected criminals to mainland China, where human rights abuses are rife and death sentences common.

[82][83] Despite the ongoing COVID-19 pandemic, Howard X continued to show his support for Hong Kong city's pro-democracy movements where he was sometimes spotted by the media.

In the interview, Howard X also revealed that he had maintained his pudgy physique through a strict regime of not exercising and eating a lot of quality steaks but he still weighs about 50 pounds less than the tubby tyrant.

As a professional impersonator of Kim Jong Un, he often makes use of and owns a number of replica BB guns, missiles and nuclear bombs for his performances and videos.

Since he was required to report to the police station every six weeks, he made sure to arrive in character with his inflatable missile to highlight the ridiculous grounds of his arrest.

[94] Reportedly, Howard X has also been using his likeness to perform humanitarian works to help another impersonator Abbas Alizada who was known as Afghan Bruce Lee, to flee a war-ravaged country.

[95] On Friday 13 May, Howard X disrupted an event at an electronics factory in Mount Waverley, Melbourne, while the Prime Minister Of Australia, Scott Morrison was visiting with Liberal MP for the Division of Chisholm, Gladys Liu.

The event occurred amidst heightened tensions between Australia and China, and investigations into Liu's possible affiliations with the Chinese Communist Party.

[100] In September 2023, Howard X appeared on a stream by popular Kick streamer Adin Ross in a staged 'interview' mimicking the central theme of the film The Interview, receiving a peak viewership of 700,000 in the process.
