Dragon Ball: It was previously set that Wukong could become a giant ape. Why didn't Saiyan become an ape-man in the later period?

The Saiyan in Dragon Ball can be said to be a unique fighting nation, which can not only be transformed into a violent and strong giant ape to increase its strength tenfold, but also become a super Saiyan to achieve all-round growth. However, with the development of the plot, the only remaining Saiyan gradually gave up the transformation of the great ape and devoted himself to the development of the super Saiyan form. Why?

Consumption of physical strength I estimate that the physical strength of the great ape will increase by hundreds of times in every super-competitive mode, so this ten-fold transformation with agile consumption and extremely energy-consuming is almost useless. Super 2 is normal 100 times, and twice as high as super 1. Exceeding 1 is 50 times normal, and the physical strength consumed is twice that of exceeding 1. If it is possible to transform into a great ape first, the combat effectiveness will become 10 times normal, and the physical strength will be 20 times that of 1 when transforming into super 2. Wukong also mentioned that muscle transformation consumes more physical strength, so it turns into a giant.

? It is easy to injure teammate Saiyan by mistake. When he becomes a gorilla, he is really a gorilla. Not only did he step out of the step of disowning his six relatives, but even his parents were in front of him, let alone his friends. Therefore, Saiyan people will not consider using ape-man form to fight against others, regardless of whether there are people around. Not only is it easy to get into other people's way, but it is also afraid of hurting teammates. Especially teammates or their own kind, maybe two gorillas will fight. After the battle, your opponent is alive and well, but you are all injured and a little lost.

If Saiyans want to become gorillas, there is a necessary condition, that is, the tail is equivalent to the medium for Saiyans to become gorillas, and it can only be done under the full moon. However, the full moon can already be completed manually, so the most difficult thing is the tail. However, the Monkey King's tail was cut once by Yamcha on the early Dragon Ball, and then by Master Roshi at the first martial arts conference in the world. Finally, it was directly sealed by the gods, which made the Monkey King's tail never grow again.

It is indeed a good choice to improve combat effectiveness and destructive power before becoming a great ape. In particular, Vegeta, a great ape who can remain rational after becoming a great ape, is a killer. Such a huge body is not only not bulky, but also agile. However, after the super Saiyan appeared, it was not only the same size and human form, but also far more powerful than the great ape, so the great ape became tasteless.
