Kiss is a humanoid Stand with an athletic build, similar to Ermes'.
It wears a dark jumpsuit along with light shoulder pads, knee pads, and gloves sharing a metallic texture. Along the middle of its torso is a vertical studded metallic slab engraved with its name, "KISS", and the letters are contained in separate circles.
Its head also has a metallic texture, and is bald except for a couple of straight spikes pointing upward with round edges, giving it the appearance of a crown. There are two studs on the sides of its head which resemble ears.
Kiss is covered in lip-designed stickers, particularly on the neck, arms and head. There are also individual stickers placed in between each letter on its torso.
Stickers: Kiss is able to place lip-designed stickers on objects, causing them to rapidly produce an exact copy of the original. When the sticker is removed, the two fuse back into one almost immediately and with great force, causing a fissure and effectively damaging the object. These stickers can be used effectively by re-fusing two objects together when an enemy is standing between them, or re-fusing an enemy's body part to cause damage. The user can also double their own body parts to block an oncoming attack, but the body part must eventually re-fuse, and can do so non-harmfully.
