"Yeah.... there is not SS3 gogeta.... yet. But lets see.... Janemba a being close or on a SS4 level managed to defeat a SS3 Goku like he was nothing. A Super Saiyan 1 Gogeta managed to pwn Janemba like he was nothing. So a SS3 one is overkill. "
just because Janemba was stronger then SS3 Goku doesnt make him anywhere as strong as SS4 sorry that wont work.
