A Kappa-based Mechasaur who appears in Episode 10 of Getter Robo.
Emperor Gore has gotten Mechasaur Buzz to be made. He test the new Mechasaur out by having him appear in the sea and try to conquer the sky by launching his buzz saws. Buzz has been destroying planes with his buzz saws whenever any of them were passing through his location in the sea. Seeing the test as successful, he calls Buzz back to have more work done on him. After the work is done on Buzz, Emperor Gore sents him out to fight against Getter Robo. After a destruction of another plane was reported around a rocky area, Professor Saotome sends out Michiru to investigate the area. When a Michiru investigates, Buzz launches his buzz saws and manages to hit her through a giant crack from underneath the rocks. When Musashi, Hayato, and Ryoma appear, they form into Getter-2 and try to get Buzz out with Drill Storm. Buzz, however, launches his buzz saws at them and manages to climb out and up a rocky cliff. Hayato then uses Getter Divide and destroys the rocks in the area, giving Buzz no place to hide now. Ryoma then changes into Getter-1 and Fire the Getter Beam at Buzz. The beam knocks the Mechasaur off the rocky cliff. Buzz then launches his buzz saws at Getter-1, but Ryoma use the Getter Tomahawk to deflect the buzz saws. However, when Getter-1 tries to fly up, Buzz hits the Getter Wing, disabling Getter Robo's balance and can't use Getter Kick on Buzz. So Musashi changes into Getter-3 and tries to grab Buzz's body. However, the Mechasaur has a buzz saw in it's chest and uses it to cut at Getter-3. So Musashi uses the Getter Missiles on Buzz, allowing him to grab the Mechasaur's tail and throw him over another Rocky cliff. Musashi then has Getter-3 jump down the Rocky cliff, but with parachutes deployed from the back. When Buzz gets up, Musashi fires the Getter Missiles again, but Buzz destroys them with his buzz saws. When he cuts the parachutes off, Musashi uses this to crush the Mechasaur to the ground. After crushing it, Buzz is finally destroyed as he explodes.
