Rocket Raccoon.
Created by Bill Mantlo and Keith Giffen, Rocket is the lovable bad-ass, gun wielding, master tactician, anthropomorphic raccoon of the Guardians of the Galaxy. Originally acting as the "Guardian of the Keystone Quadrant" he captained his own ship with fellow side kick Wal Rus before eventually winding up on Starlord's team of Guardians by Dan Abnett and Andy Lanning. With new buddy Groot, Rocket has become a core member of the Guardians of the Galaxy and a fan favorite. So much so that he will be in this years GoTG movie.
But does everyone love him? What say thee Realmlers?
I, of course, can't live without him and buddy Groot.
As a side note, I am particularly saddened by the tragedy of Rocket's creator, Bill Mantlo. On Friday, July 17, 1992 Bill was struck by a hit and run driver and to this day lives in a special care facility with brain damage. The link below will give you the full story but I warn you - it's a sad one.
