Random stuff that I like to give/say about Saiyans in no particular order (and probably other people have said this as well):
• Size does matter. In height that is, because if you have a tall and a short Saiyan and expose them to the moon the tall Saiyan will have more control over themselves meanwhile the short Saiyan is just a monkey full of rage.
• Saiyans always have a physical aspect that makes them strong even if they have a low power level. For example:
— Bardock, Goku, Raditz, Gohan, Goten and Pan, all of them have a very thick and strong skull that allows them to deal an amazing amount of damage with their headbutts. But in Planet Vegeta this trait was always joked on because when the Saiyans with it reached puberty would spend hours on end hitting their heads against rocks until they broke.
— King Vegeta, Vegeta, Tarble, Trunks and Bulla, they have an incredible bite force that is closely followed by big and durable teeth and fangs.
Now this one was really respected in Planet Vegeta but it didn't mean you couldn't laugh at it because children with it were dangerous as hell, they will bite anything and everything within their reach, and these children were also the reason some Saiyans had short tails, because the kids could bite them off.
— Paragus, Broly and Turles have a really strong grip, and when it comes to the Ozaru form this one tends to have big claws.
Now this type of Saiyans always kept their arms as close to their body, and their hands were always closed, so really there wasn't much to poke fun at, but if you were in a relationship with a Saiyan with this trait you were very much considered lucky for "opening their hand".
• There's also the body language of the tail, because while I think that it mostly resembles the typical movements of monkey/cat tails there tents to be some uniqueness to it, and I have two examples.
— The first is when two Saiyans who are close friends or partners and some random wants to pick a fight, if Saiyan A does want to fight this person but Saiyan B doesn't want to then Saiyan's A tail will get a grip of Saiyan's B forearm. The reason for this is to make it clear to take you want to be taken out of the fight (after a few hits).
— And the second one is sex actually, basically it's Saiyan's A tail grabbing onto the forearm, thigh or waist of Saiyan B and slowly moving up and down in whichever part the tail grabbed. And as you can guess this signals that Saiyan A is interested in having sex with Saiyan B and is kinda like a courter ship.
I'll leave this like this for now, if there're any writing mistakes you can let me know, bye bye
