Lee Junho's 'Cashero' Hits Netflix Today: Is This the Most Relatable Superhero Yet?

What if your bank account balance determined your superpower? Actor Lee Junho is back with a concept that feels uniquely 21st-century. As of December 26, 2025, his new Netflix series 'Cashero,' based on the popular webtoon of the same name, is now streaming globally.

A Hero as Strong as His Cash

According to reports from outlets like Soompi, 'Cashero' follows Kang Sang Ung (played by Lee Junho), an ordinary civil servant who discovers he gains superhuman strength proportional to the amount of cash he's holding. It’s a clever twist on the superhero genre, grounding extraordinary abilities in a painfully ordinary reality. When he's broke, he's just a regular guy; when he's holding a wad of cash, he's a force to be reckoned with.

Lee Junho's New Challenge and the Webtoon Advantage

The series marks a significant new role for Lee Junho, who is widely acclaimed for his roles in romantic and historical dramas. Taking on a superhero role is a fresh challenge that has generated considerable buzz. The show also has a built-in advantage: it's based on a highly successful webtoon. This strategy of adapting established webtoons provides a proven storyline and an existing fanbase, a formula Netflix has leveraged for numerous K-drama hits.
