2 wanting your thoughts

So I'm think about creating my own version of the Z-fighters, that will interact with the original Z-fighters. These new guys will be a mix of humans and aliens but there wont be many, maybe just 3 to 5 of them. There will be almost one human but I'll be giving him or her strong potential and and interesting power. The others will be aliens that arrive on earth but they won't be raced that exist in the DBZ universe, atleast not till I create them. As we know there are normally years in between threats to the planet so I plan to have some new enemies show up so that our new fighters can get experience. It's a big world so it's not like goku and the rest can handle it all. But don't worry they won't play second fiddle to the Z-fighters, they will be just as strong if not stronger, since our MC is a reincarnated person and will have ways to strengthen himself and his teammates.

The human will be his beat friend, like krillin is goku's best friend. They will be together since a young age so being best friends is a given. Each one of the main members of these new fighters, let's call them X-fighters if you can think of a better name let me know, will become gods of their respective race in the future.

Each of the X-fighters will get a spouse from the temporary fighters that join their team but end up disappearing cause they arent strong enough. since ima be creating them I dont want the hard work I put into making them be wasted and like trunks and Gohan that are kids of the Z-fighters it opens options of me creating characters like them later on.

Now the ideas I wanted from you is what do you think the characteristics of these new races should be? And what do you think the names of the races would be?

The current X-fighters will include right now, will be our MC, his human best friend, and a female saiyan that ima make. a little back story on that saiyan is that her parents had the same idea as goku's parents. And yes she like goku had a low battle power when born.

since I have three permanent X-fighters already I need two new races. One will will be female while the other will be Male. It's my belief that there arent enough powerful females in the story of DBZ, so I wanted to make some.

P.s. these new races can be from legends or myths of ours like the Japanese yokai or they can be a new species that rivals the saiyans like in a fan fic that I read where a guy created a race of tiger people that are like the saiyans but tigers instead of apes.

Also I may or may not add a sixth member to our X-fighters. This sixth member will be a mage if I add it. since magic exists in the DBZ universe but isn't seen all that much. if I do this she will be tech smart like bulma, but be much stronger than bulma, so that I can create magitech.
