Half Human Half Saiyan speculation It says in the article that half saiyan s bodies are weaker than full saiyans but as far as I can tell this is purely speculation The fact that during the final battle with Cell Gohan was stronger than his father at a far younger age shows that it s simply not true Goten and Trunks were also both halfbreeds and since they both acheived super saiyan at a young age were both stronger then their fathers at the same age Half saiyans not being able to acheive Super Saiyan 3 is also pure speculation since Goten Gohan and Trunks all stopped training hard at the end of DBZ logically they wouldn t have gotten there In any case Goku was the only case of SSJ3 to ever occur so it s very fuzzy in the area The real proof that it s wrong however is that Gotenks could go SSJ3 Though you could argue that the two saiyan halves double over making him pure saiyan this wouldn t make sense from a genetic point of view In other words Gotenks was a half saiyan and he went SSJ3 so there is no proof to say an unfused halfbreed couldn t achieve it if they became powerful enough I m making slight edits to remove those comments
