A Crimson Jazz has a smooth, conical, red body with a Heartless emblem emblazoned on its chest and a yellow flame pattern decorating the base of its body. 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, red hat that is yellow on the inside and has a jagged brim and a thin, curled tip. Like many Heartless, the Crimson Jazz has glowing yellow eyes. Its seemingly useless feet sport three small, thin toes. The Crimson Jazz is one of the largest members of its family of Heartless, only contested by the likes of the Emerald Serenade and Pink Concerto.
The Crimson Jazz, like many other Heartless in its family, is named after a color—in this case, crimson, a shade of red—and a musical term—in this case, jazz.
The Crimson Jazz, the largest Heartless of its kind, it is a powerful relative to the Red Nocturne, and can be a real danger if not quickly destroyed. Like its predecessor, it utilizes Fire magic. However, its magic is more focused on surrounding and crushing the target with explosions rather than shooting flames. Crimson Jazz attacks with exploding mines that follow Sora until they explode. Even after a Crimson Jazz is destroyed, any existing mines will still follow Sora until they explode. And with magic-resistance and having the airborne trait, this Heartless can pose quite a threat. This Heartless has a small fire pattern along the bottom of himself and just appears to be a bigger version of its predecessor.
In an open area with two or more Crimson Jazzes, Sora can be pushed up very high by the chain of the their small mines exploding. For this, Sora should use Aerial Recovery and Aerial Dodge to keep himself aloft for a while. As the bombs do not do heavy damage, this can continue without great danger to Sora, sometimes happening unintentionally. Use Reflect to end the chain as fast as possible. Fire magic does not harm them, so it is not recommended to use it to inflict damage.
