It was the year 2181. The ReploidWars had taken their toll on humanity. The survivor count low, and the Maverick count high, two unlikely parteners joined forces to attempt an escape. An Escape under the Seas. One of the founders, and creators of the new colony was Chief Technician Galboa Stronghelm. He engineered the creation of Kaitei. The second was a mage known only as Steele. She helped form many other aspects of the colony. Together they formed the Under Seas Resistance where they hoped to live with little or no Maverick activity.

Dreams are dreams, no matter who you are, and all shall crash down apon you without the proper foundation. So it was true for Kaitei. The Maverick Virus had a new strain, one they were not prepared for, and soon the Aquatic-Roids were infected too.

Not all hope was lost... in fact, thanks to the expansion of other colonies it seemed that Kaitei may have a fighting chance.

Now was the time for warriors! Now was the time to stand! The era of Disposable Heros was at hand!
