In the comics published by ImageMichaelangelo's interest in writing is expanded upon and he's established as a writer of fiction and poetry. An early issue has him selling his first poem to poetry digest. As the comic continued, Michelangelo's career as a writer gradually expanded. In the final issue, he has published his first novel, a romance called "A Rose Among the Thorns". April O'Neil mentions that the book was already going back for a second printing and that she'd heard that Oprah Winfrey loved it which, "Practically guarantees that it will be a best-seller."
Michelangelo, while never severely injured like his brothers, he still had his own missions to deal with regarding Shadow.
Michelangelo is the only turtle who did not end up disfigured in some way; Leonardo lost his left hand and had it replaced by a steel cap with a retractable blade, Raphael was facially disfigured after being shot in the face, and Donatello was transformed into a cyborg after being shot and thrown out of a helicopter.
