So, I've heard of a few cases in which a new user wanted to make a race we didn't have, and was forced to pick from the dreaded 'Alien' race. Now, don't get me wrong, I'm not saying the alien race is bad, it's just that with all the races there are in DBZ, we have a small amount, comparitively. There are several more DBZ races to choose from, and I feel like adding a few more would expand our horizons and add more variety to the wiki rather than just having a bunch of races dumped into the Alien category. (Though we'd still keep it). Of course, we can't add them all but we can add some popular ones.
Here are some potential races to add:
Hera-Seijin, aka The Race of Hera, aka Bojack's race.
Konats aka Tapion's Race.
Shin-jin aka The Kai race. Please note that this is BEFORE they become kais.
Makaioshin, which are evil shin-jin. Could be incorporated as legendaries.
Brench-seijin aka Salza and Jeice's race.
These are just a few, but it should be enough. Let me know if you like the idea. I'd be fully willing to help implement these races, if you'd like.
