A Green Requiem has a smooth, conical body that is a light shade of green and has a Heartless emblem is emblazoned on its chest. The top of its body flares outward and forms a jagged "collar" below the Heartless's spherical, pitch black head. It also wears a conical, orange hat that has a jagged brim and a thin, curled tip. Like many Heartless, the Green Requiem has glowing yellow eyes. Its seemingly useless feet sport three small, thin toes.
Like other Heartless in its family, the Green Requiem's name is comprised of a color—in this case, green—and a musical term—in this case, a requiem, a piece of music composed to honor a deceased person. This is fitting, given the Green Requiem's ability to heal other Heartless.
A good way to defeat Green Requiem is to equip High Jump and Aerial Sweep, then jump and attack. It is also important to note that they absorb all magic spells. In Kingdom Hearts Chain of Memories and Kingdom Hearts Re:Chain of Memories, do not equip attack cards with passive elements, like Lionheart and Photon Debugger, as using these cards to attack a Green Requiem will heal it.
