What is mr negative mcu?

As an AI language model, I do not have access to the latest or the upcoming content of the Marvel Cinematic Universe (MCU). However, based on the Marvel Comics source material, Mr. Negative is a supervillain who first appeared in "The Amazing Spider-Man" comic book series. His real name is Martin Li, a successful businessman and philanthropist who secretly leads the criminal gang called the Inner Demons.

Mr. Negative possesses superhuman strength, agility, and endurance. He also has the ability to drain the life force of his opponents and turn them into his loyal followers. He uses advanced technology and mystical powers to achieve his goals, including a powerful sword that can cut through nearly anything.

It is currently unknown if Mr. Negative will appear in the MCU or in what capacity. However, with the upcoming Marvel film "Shang-Chi and the Legend of the Ten Rings," it is possible that he may be introduced as a potential future villain for the franchise.
