Monty Oum, Rooster Teeth animator, died on Sunday after suffering an extreme allergic reaction at the age of 33.

Monty Oum DEAD

Rooster Teeth announced the sad news with a statement on their official website released Monday. “Our friend, inspiration and co-worker Monty Oum passed away yesterday afternoon at 4:34 p.m. surrounded by people who loved him very much,” reads the statement.

The company announced that Oum had been hospitalized on Friday, Jan. 30, but Oum had reportedly been in the ICU for a week before then. “Ten days ago Monty suffered a severe allergic reaction during a simple medical procedure that left him in a coma. Although he fought bravely, his body was not able to recover,” said Rooster Teeth.

Rooster Teeth created a GoFundMe page in an effort to raise money to help cover Oum’s medical costs. 9,256 people donated to the fund, which raised $223,036 in 3 days. Oum is survived by his wife, Sheena, his father and six brothers and sisters.

Finally, the company asked that fans honor Oum with creativity instead of flowers or gifts, saying, “Use your imagination to make the world a better place in any way that you can. If you know Monty like we do, then you know he would certainly be doing that if he were able to.”

I only met @montyoum once. He graciously skyped into my review show for RWBY. He was kind, funny, & talented. Can’t believe that he’s gone.
