The Undersea Defender Unit was designed as a defensive protector of underwater bases and strategic points. The Unit features posable fingers and a Tidal Harpoon Cannon. Due to the Unit's function, it also is equipped with a Deep Sea Defender Array, a turret emplacement that the cannon can be stored in. In submarine mode, the Unit can store it's cannon underneath the hull and can combine with the defender array. This arms the Unit with Mini Pulse Blasters, an Echolocation Array mounted on the rear and gives it the ability to convert to a more agile "Attack Form". The Unit is capable of combining with the defender array in robot mode to create the Guardian Form. The Unit continues to have possible fingers and converts it's cannon to a Piercing Power Staff. It also gains sensory array capabilities from the combined form's horns and can create powerful shockwaves through it's kicks.
