Not quite perished, although some days I wish I had.

— Martin of the Opera's unlock message.
Martin of the Opera is a limited-time character that was released on November 6, 2019, as part of Act 3 of the Treehouse of Horror XXX Event. He is unlocked upon the placement of the Underground Piano. Together with the Underground Piano, they were the fifth and final prizes to be won in the event's Act 3.
Martin was at a science fair at Springfield Elementary but there was an explosion. He was thought to have been killed, but he survived, although he admits that on a few days, he did wish that he had died on that day. He lived the rest of his life like the Phantom of the Opera under the school, playing music on an electric pipe organ.
