Goku...Super Saiyan?

Goku begins to fight with Recoome after he gives Gohan, Krillin, and Vegeta Ginsu Beans. Recoome powers up for a Recoome Kaboom, after the scouter reads that Goku's power level is only 5,000. He thinks he can beat Goku easily. But, Goku is concealing his power, and only Vegeta, Gohan, and Krillin know it. Recoome starts to attack, but then stops dead because Goku elbowed him in the stomach, taking Recoome down. Jeice and Burter are surprised, but not worried...Vegeta begins to wonder if Goku is a legendary Super Saiyan. The last Super Saiyan (who lived hundreds of years ago) could only maintain his power in the transformed state, and he could not control it. Goku, however, was in complete control, and had lost his tail permanently as a boy, so he could not transform. Jeice and Burter start to attack. Goku just stands there. Or is he moving? Vegeta sees foot prints in different spots, so he must be moving. But, how could even a saiyans eyes not even sense the movement? Goku begins to fight back, and makes a fool of Burter and Jeice. He defeats Burter, and tells Jeice that he can leave, unscathed, as long as he leaves the planet. Jeice flies away, but he does not leave Namek.
