Question: What person wrote the song that inspired Marvel Comics' character Rocket Raccoon?
Context: Cipher (Jennifer Swann) is a fictional character appearing in American comic books published by Marvel Comics.  The character appears in the newuniversal imprint of Marvel Comics, and is one of the four initial superhumans created by the White Event in 2006 (the others being Justice, Nightmask, and Star Brand).  "newuniversal", designated Earth-555 in the Marvel Comics multiverse, is a re-imagining of the New Universe imprint from the late 1980s.  The name Cipher actually refers to two things: a powerful extra-dimensional glyph (tattoo) that confers superhuman powers on a sentient being, and the name of the being that wields the glyph.  Cipher is a new superhuman created by Warren Ellis and Salvador Larroca who were inspired by the original Spitfire and the nature of the Star Brand itself (as an extra-dimensional tool of near-unlimited power), combined with strong conceptual ties to Iron Man. Rocket Raccoon was a four-issue comic book limited series that was published in 1985 and featuring the eponymous character.  It was written by Bill Mantlo, penciled by Mike Mignola and inked by Al Gordon (Issue # 3 was inked by Al Milgrom).  All covers by Mignola and Gordon.  The series took place on half world where Rocket and his anthropomorphic allies fought killer clowns with lethal juggling balls and deadly unicycles and who spoke in a stilted language full of alliteration and rhyme.

Captain America is a fictional character appearing in American comic books published by Marvel Comics.

Namor the Sub-Mariner ( ) (Namor McKenzie) is a fictional character appearing in American comic books published by Marvel Comics.  Debuting in early 1939, the character was created by writer-artist Bill Everett for Funnies Inc., one of the first "packagers" in the early days of comic books that supplied comics on demand to publishers looking to enter the new medium.  Initially created for the unreleased comic "Motion Picture Funnies Weekly", the Sub-Mariner first appeared publicly in "Marvel Comics" #1 (cover-dated Oct. 1939) – the first comic book from Timely Comics, the 1930s–1940s predecessor of the company Marvel Comics.  During that period, known to historians and fans as the Golden Age of Comic Books, the Sub-Mariner was one of Timely's top three characters, along with Captain America and the original Human Torch.  Everett said the character's name was inspired by Samuel Taylor Coleridge's poem, "The Rime of the Ancient Mariner".  Everett came up with "Namor" by writing down noble sounding names backwards and thought Roman/Namor looked the best.
