WASHINGTON — Jeff Garcia, celebrated for his work on “Jimmy Neutron,” has died, his son confirmed through a heartfelt Instagram post on Wednesday. The family has requested privacy during this difficult time.

Jojo Garcia shared his profound grief, stating, “With a very heavy heart, I would like to inform everybody that my father, Jeff Garcia, has passed away. My father was a unique soul. He was unapologetically himself and I will always admire the love, compassion, and drive that he had. He taught me so much and gave me advice that I live by every single day.”

“He was a Father, Son, Uncle, Cousin, Brother, but most of all, he was my best friend. I would call him every day. I would tell him about the plans I had in comedy and my life. He believed in me, in a way that nobody else did,” Jojo continued. “The talent my father possessed was truly one of a kind. From voice acting to stand up comedy, he shined with his quick wit, brash humor, and charm.”

Garcia was widely acclaimed for his portrayal of Sheen Estevez, a beloved character among Jimmy Neutron’s circle. Aside from his iconic voice work, he was also a gifted stand-up comedian.

The comedian was most known for his role as Sheen Estevez in Nickelodeon’s “Jimmy Neutron” franchise, playing one of Jimmy Neutron’s best friends. Garcia was also a stand-up comedian. 

“He has made such an impact on people’s lives internationally, whether you grew up watching Jimmy Neutron, or shared a laugh with him at one of his shows. He was my hero… I idolized him,” Jojo added. “He may be gone, but he will NEVER be forgotten. He lives on through our family and friends he loved so dearly, along with the legacy he has created. I know you’re in heaven smiling down and you’re in a better place now. No more pain. I’m going to make you proud pops. Fly high, Rocket Man.” 

Jojo did not share a cause of death for the comedian. 

TMZ reported Wednesday that the voice actor was hospitalized on Dec. 8 due to difficulty breathing and that his lung collapsed the following day. He suffered a brain aneurysm earlier this year after a fall and had a stroke several weeks ago, TMZ reported. 

“Jimmy Neutron” co-star Debi Derryberry, who voiced the titular character, honored Garcia in an Instagram post following the news of his death.
