Watch Science Ninja Team Gatchaman online: Episode 90 Armoured Mecha Matanga

Joe, who is busily maintaining his weapon, is told by Ken that using weapons is a mistake, which results in a dispute. Before his father's grave, Ken is wondering whether, even if they defeat Galactor, a new evil organization will be born. On Mikron Island, there's a extinct volcano in the middle. Around it, seven evenly-dispersed cities are expanding. The mecha Matanga takes place on top of the mountain and sends a message to Nambu which says that it will attack a city every twelve hours as long as Nambu doesn't send the Science Ninja Team. The Science Ninja Team goes to the island, but Ken makes only consecutive photos of the mecha and goes back to the base. He has the photos developped and examines them, looking for a weak point in the mecha. If they would blow up the mecha with its thick armour, the whole island would be destroyed as well. Soon, Ken notices that the mecha has a vent and asks Nambu to manufacture a special bullet. The Phoenix opposes the mecha, standing still in the air. At its tip, Joe aligns the Condor Machine, which is loaded with a single special bullet. Ken's instructions are to shoot the bullet through the vent, which measures a bit over one centimeter. The interior of the mecha then becomes a sea of fire. The mecha clutches the God Phoenix to its chest and heads for the sea. Ken, betting that the belly armour is thinner, has Jun's rocket fired into it from the top dome. Ken wins the bet. The mecha is blown up by the rocket.
