A Creeper seems to dress in a baggy, light grey jumpsuit with dark grey legs. Its lower legs fan outward like the lower half of the Nobody symbol, and its feet are nearly featureless, black points. Its arms are very long, light grey, and its hands are flat and teardrop-shaped. The back of each hand sports a white Nobody logo. The Creeper's grey head also has a teardrop shape, albeit one that curves to its right. The Nobody's feet dangle uselessly, while it uses its wide, flat hands to move. Like all Nobodies, Creepers maintain an astounding ability to contort themselves. The Creeper also displays the ability to shape shift, turning into a large lance similar to the ones used by the Dragoons, a large sword, and a small, hexagonal shield. It can also turn its arms into small wings. Creepers appear in a different manner than most Nobodies; they sometimes seemingly appear from nowhere, as opposed to the distinctive, thorny portals most Nobodies come from.
The Creeper's name refers to its tendency to crawl using its hands rather than its feet.
The Creeper is the weakest of all Nobodies. Its anatomy gives it an awkward mode of mobility. As it moves, it swings its small feet in the air. Creepers can change their shape into various forms, including a shield, spear, mask, and sword. This can mirror many of Organization XIII's weapons. They tend to appear in high numbers, and usually accompany Dusks. When Creepers first appear, they do not have the head point or front legs, and are hard to discern whether they have a definite shape. Instead, they copy Dragoons by curling up into a ball shape and disappearing, then coming down on top of you and giving you damage. Similarly, Creeper Nobodies will never appear in a weapon-shaped form, but will always appear in their basic form, and may change shape during combat.
Creepers will always appear in groups, either composed entirely of Creepers or with other Nobodies. Because of this, it is best to defeat them with wide-range attacks and spells. For example, Thunder spells and the Explosion combo finisher can both eliminate several Creepers at once. The use of the Magnet spells are a similarly helpful tactic when battling several Creepers, since it allows you to use short-range tactics to defeat the Creepers, though at the cost of more MP.
Battling several Creepers can be used to level up Final Form very quickly, since you receive one point for experience for each Nobody defeated. Creepers usually appear in large groups and are easy to defeat, so they offer quick experience when leveling up Final Form.
