Michael Wildshill, CEO of Universal Animation and Founder of Gingo, dead at 66

(CNN) - Michael Wildshill, a man who founded Gingo Animation and Universal Animation while being the current CEO of the latter, created some of the most successful franchises like Gabriel Garza, Agent Chrysocolla, among others died Wednesday, according to Wildshill's wife Ashley Wildshill.

He was 66.

"He was diagnosed with this brutal, relentless form of malignant cancer only day ago," Paul said in a statement he provided to CNN. "In that time, it managed to spread rapidly throughout his system to the point where it was too late; the only mercy it exhibited was its sharp and swift execution. Michael did not suffer. He did not have to lie submerged in pain. For that, we are grateful."

Ashley first shared news of his cancer diagnosis last month.

At the time, his wife said that his health was "serious" and that Wildshill was in the hospital since January after a near fatal heart attack.
