You are watching: Why does trunks not have a tail
Dating ago to the original Dragon Ball, Saiyans have actually been feared not only for their toughness yet additionally because they transdevelop into giant Great Apes when the moon is full. Up till the Saiyan Saga, we watch Goku, Gohan and also Vegeta transcreate right into these King Kong lookalikes but after that, never before aacquire. It"s rumored that creator Akira Toriyama simply foracquired about the tails, so Goten and Trunks never before had actually theirs. But what are some in-universe reasons we have the right to usage to explain this?
Goku causes mass damage and also also the fatality of his adoptive grandpa, Gohan, once he transforms. Goku had actually his tail cut off a complete of three times throughout the original run of Dragon Ball. His boy, likewise called Gohan, would certainly go on to inherit this trait, though Chi-Chi and Goku make certain he does not see the moon. It isn"t till Piccolo takes him out into the wilderness that he sees the moon for the first time, and also hence transforms into his Great Ape develop, much to Piccolo"s surpincrease. Piccolo then destroyed the moon and yanked the tail off.
In the anime, it grows ago and also Piccolo when aobtain removes it, however it grows back throughout the fight through Vegeta (both in the anime and also the manga). With the exemption of GT, which many fans do not think about canon, the tail never renders an appearance aget.

The Daizenshuu overview series clarifies that a tail will grow earlier if the Saiyan is in prompt peril, as we observed with Goku in Dragon Ball. The guide publications were originally printed in 1995, through an updated, even more condensed variation released in 2013. In Dragon Ball Z: Kakarot, it"s explained that when a tail is cut off, there"s an eight percent opportunity for it to prosper back and that it won"t grow ago at all if the Saiyan surpasses the power of the Great Ape develop without having actually transcreated into it.
Thus, if a Saiyan reaches Super Saiyan without being in Great Ape form, the tail will not flourish earlier once being reduced off. If they reach Super Saiyan while in Great Ape create, the tail has actually an eight percent chance to grow back. Due to the fact that the latter information came from a video clip game released this year, it isn"t clear whether this information is considered canon or not.
A clinical basis for this can be that considering that both Vegeta and also Goku married human beings, the trait ended up being recessive, and also Gohan just so taken place to have inherited it, while Trunks, Goten and Bulla didn"t thrive them. If you have actually brown eyes and also your spouse has actually blue eyes, then you have 4 youngsters, tbelow is a 25 percent opportunity that one of those kids will have actually blue eyes given that they are recessive. Due to the fact that there are 4 Saiyan-human hybrid children, it would certainly make sense that at leastern one of them would certainly have actually a tail if the gene ended up being recessive. Gohan, the earliest, just so happens to be the one to inherit it.
Fans on Reddit likewise speculate that the younger youngsters did, in fact, have tails, yet Chi-Chi and also Bulma had them removed to proccasion them from transdeveloping into the Great Apes. Throughout the Buu Saga, Trunks and also Goten were able to reach their Super Saiyan forms at an extremely young age, so it renders sense that they would certainly not rethrive their tails as soon as that had actually got to that allude. This doesn"t define why Bulla didn"t have actually a tail once she was born, but the trait might have been recessive in her instance.

While the agreement is Toriyama just foracquired to draw them on the kids, there are numerous in-cosmos factors why they do not show up again after the Saiyan Saga that fans deserve to consider. It can be scientific research, it could be new lore, or it could just be headcanons. But the agreement is that the tails were a hindrance to the Saiyan"s development in power, so maybe it"s better that they"re gone for excellent.
