Floaters are a species of strange, jellyfish-like creatures that began to grow more and more prevalent as time went on and as the first phase of the Second Tiberium War was drawing to a close. Floaters float over the battlefield, releasing Tiberium gas to move them through the air. The gas is dangerous to infantry, potentially turning them into visceroids. To attack vehicles, they typically latch on the vehicle to both tear it apart with its tentacles and send vast quantities of electricity through the target.
Floaters represented a significant threat to almost anything in their vicinity; it could take several heavy vehicles to bring just one of them down, and a single floater was more than a match for a GDI Titan or a Nod Tick Tank. In at least one instance GDI forces actually had to coordinate an armored defense to protect and evacuate civilians due to the threat of attacks by groups of such creatures.
Furthermore, the floaters' electric attack, which is used when in contact with the target, grappling and shocking it, is extremely effective against both vehicles and structures. The floater can even prevent the vehicle it was attacking from firing. It was not seen after the Firestorm Crisis for unknown reasons.
It is unknown what manner of creature was mutated into the floater. Currently the best estimates would be the jellyfish, as there are many obvious similarities between this species and the floater.
The Tiberian Floater is mostly seen in the Genesis Pit. But is seen many times on other levels. The Tiberian floater can turn infantry into Visceroids using its tiberium gas attack.
