Michael Kopsa, a veteran actor who rose to fame through "The X-Files" and "Fantastic Four," has died at the age of 66, multiple news outlets confirmed.

Kopsa's ex-wife, Lucia Frangione, delivered the heartbreaking news through a tweet. She disclosed that the 66-year-old died on Sunday.

The same statement disclosed Michael Kopsa's cause of death.

"The great Michael Kopsa, my dear friend and the father of my child, Nora, passed away on Oct. 23, 2022, of a brain tumor. He was an incredible stage and screen actor, voice actor, carpenter, musician and painter. Most importantly, he was a loving and richly present father," she said.

The former wife did not share when Kopsa was diagnosed with a brain tumor. However, Cancer.net notes that a cancerous brain tumor can have a 36 percent 5-year survival rate and a 31 percent of 10-year survival rate.

According to Johns Hopkins Medicine, meningioma is the most common brain tumor, and it can be benign. Some of the complications the dreaded condition can cause include headaches, hearing loss, balance issues, and seizures.

Following the announcement of his death, people paid tribute to him and remembered the contributions he offered to the industry.
