SCP-2129 is an invisible entity manifesting itself by a continuous stream of detonations. It possesses the ability to levitate and fly in three dimensions, and detonations happen continuously while the creature is moving, with a general frequency of two per second. It has been theorized that detonating is either its means of energy production or a side-effect of it. Likewise, study of the creature's flight patterns have shown changes of directions correlated to its detonations. Thermal cameras show, in the absence of explosions, an oblong, serpentine body approximately a meter long, with no other discernible characteristics. Experiments to discover more about the characteristics entity's physical body are currently being devised.
