Writer and artist Ty Templeton, known for his work on The Batman Adventures, Batman '66 Meets Green Hornet and his own Bun Toons, is in a medically induced coma after suffering a heart attack.

"The plan is to take him off both the sedatives and the ventilator tomorrow," his wife, colorist and letterer KT Smith, wrote overnight on Facebook. "[...] He is in critical but stable condition. His location will change in the next few days depending on his condition."

Inducted last year into the Canadian Comic Book Hall of Fame, the 52-year-old Templeton has a long list of credits that also includes Simpsons Comics, The Batman and Robin Adventures, Batman: The Brave and the Bold, Star Trek: Mission's End and Spider-Man/Human Torch. An Eisner nominee and Shuster Award winner, he's known in Toronto for his writing and drawing classes "Ty Templeton’s Comic Book Boot Camp."

Smith encouraged well-wishers to email Templeton, saying, "I will make sure he sees them when he is able."
