The good Bio Ninjas rule the continent of Atlantis, the largest of all the continents on Planet Zerin. The Bio Saurus, allies of the good Bio Ninjas, rule the continent of Poseidon. The dark Bio Ninjas rule the continent of Legend and the Bio Bugs, allies of the dark Bio Ninjas, rule the continent of Hive.
Vondar, leader of the good Bio Ninjas, commands the most powerful army on the planet. The good Bio Ninjas are in a constant state of war against the dark Bio Ninjas to keep them from of gaining complete control of Zerin.
Vondar uses his Katana sword, capable of slicing through the strongest enemy armor, to battle the dark Bio Ninjas. He can swing or spin his Katana at light speed because of his bionic arm. His side-kick, Dire Raith, has a high-speed chainsaw arm that can saw though any material found on Zerin, including dark Bio Ninja body armor. Dyment, Vondar’s Weapons Specialist, can melt a robot opponent a mile away with his flame thrower.
Using Battle Belts gives Bio Ninjas special abilities in close quarters to repel opponents at speeds of 10,000 RPM.
